Di Stefano Industrial & Power Conversion Marketing TDE1708DFT TDE1708DFT HIGH-SIDE AND LOW-SIDE POWER SWITCH IN A TINY PACKAGE Tiny DFN8 Package Housed in the tiny exposed pad, 8 lead 4x4mm DFN package, it is the best solution for cases where limited space is available (for instance in proximity detector applications). The internal output current limitation (in HS configuration) has been set at 300mA, which is very close to the maximum nominal current (250mA). This avoids useless and risky power dissipation if there is a fault due to over-current or short-circuit in the output. However, TDE1708DFT TDE1708DFT can also be used as a standard intelligent power switch in industrial applications in general. The ability to use the device in low-side or in high-side switch configuration also makes it possible to create half-bridge topologies with two TDE1708DFT TDE1708DFT devices (one in low-side and the other in high-side). 6 5 SENSOR VSS VREG IN R 3 DELAY TDE1708DFT TDE1708DFT Driven by the precise requirements from the field of factory automation and process control, ST has developed the TDE1708DFT TDE1708DFT, a tiny low-side power switch. Since this switch has two output configurations, (load to ground and load to supply voltage), it does the job of two different devices. It has numerous in-built protection functions and status indicators, plus one +5V linear regulator to supply the internal circuitry, and even the external circuity if required. This feature eliminates the need for costly and bulky external regulators. ST's TDE1708DFT TDE1708DFT is one of the few devices available on the market to provide a supply voltage as high as 50V.

Housed in a SO-8 package, they have been developed for a broad range of applications requiring space saving solutions. High current gate drivers allow the design of converters for currents from a few Amps to over 30 Amps over a wide input voltage range. Different types of control loops and protection features offer high flexibility combined with very low complexity.

The output voltage is regulated with a tolerance of ±1% over temperature and line voltage variations. The devices embody an anti shoot-through and adaptive dead-time control to minimize the low-side body diode conduction time, maintaining high efficiency and avoiding the need for additional Schottky diodes. Over-current protection, with programmable threshold, is achieved through low-side Power MOSFET sensing, thus avoiding the use of a currentsense resistor. The feedback disconnection protection prevents dangerous voltage levels to the load in case of misconnections. Soft-start and disable functions are available in both devices. Moreover, their lowside-less start-up function allows the supply of prebiased loads without generating negative spikes at the output voltage during soft-start. The L6726A L6726A provides a simple control loop with a transconductance error amplifier and soft-start programmability. The L6727 L6727 brings a high-bandwidth voltage mode error amplifier with over-voltage and under-voltage protection.

Montemezzo Industrial & Power Conversion Marketing L6562A L6562A NEW INDUSTRY REFERENCE TRANSITION MODE PFC CONTROLLER The latest device to enlarge the PFC product family, is the L6562A L6562A, a current-mode controller operating in Transition Mode (TM). As an evolution of the L6562 L6562, it has become the industry reference for several designs in LCD TVs, AC-DC adapters and chargers, desktop PCs and games, it mantains the pin-to-pin compatibility, both in SO-8 and DIP-8 packages, while offering improved performance and features. Since the new current sense threshold of 1.1V (typ.) allows the use of lower value/lower wattage sense resistors, the overall system efficiency is greatly increased. Moreover, the operating current and the dynamic over voltage protection current have been reduced to further limit the stand-by losses. The new digital blanking time and a reduced propagation delay time allow the functionality at high frequencies near to the zero-crossing, reducing the overall total harmonic distortion. By using ST's patented Fixed-Off-Time topology, the output power can easily run in excess of 400Watts.

This translates into a more advanced technology requirement with more computational power and memory in the already size-constrained silicon space of microcontrollers or microprocessors. To address this issue, ST has introduced the new Xpander Logic family to help overcome the limited number of Input/Output (I/O) por ts in the microcontroller and microprocessor based embedded systems. Any existing or additional intensive tasks on the central processing unit (CPU) can be reassigned to the Xpander Logic IC at ultra-low power consumption and in very small packages. General Purpse Input/Output Port Expansion The functions of a GPIO port expander can be obtained by upgrading the CPU with integrated features or by adding a Complex Programmable Logic Device (CPLD)/Field Programmable gate Array (FPGA). However both solutions come with their respective pros and cons: Xpander Logic Cost Solution size Power consumption Flexibility PCB routing CPU Upgrade CPLD Addition Low Medium Low Less Flexible Good Medium Small Medium Highly flexible Potentially problematic High Large Medium Flexible Good Xpander Logic Advantages Xpander Logic allows the existing system processor to use a wide range of intelligent functions through a standard and high-speed Inter-Integrated Circuit (I 2C) serial peripheral interface. All these features are achieved through a minimum change on the existing microprocessor or microcontroller's firmware. This results in a very flexible, cost-competitive solution to expand the system's resources compared to the complex implementation of a larger and more expensive CPU or CPLD in the embedded system. A further benefit of the Xpander Logic family is the high optimization for micro-power operation and www.st.com/xpanderlogic the advanced power management support that helps modern portable systems preserve and extend battery life.

A separate GPIO expander IC is often used in mobilemultimedia platforms to solve the problem of the limited amounts of GPIOs usually available on the digital engine. The STMPE2401 STMPE2401 offers great flexibility as each I/O is configurable as input, output or specific functions; it is able to scan a keyboard, provide PWM outputs for brightness control in backlighting and serve as a rotator decoder interface and GPIO. This device has been designed with very low quiescent current and wake-up features on each I/O in order to optimize the power consumption of the IC. Keypad And PWM Controller The STMPE2401 STMPE2401 keypad controller allows control on a matrix keypad of up to 8*12 keys (96 keys). The device is also able to detect two simultaneously pressed keys and uses an internal FIFO to store the key strokes when the host CPU is too busy to access the keypad data. If the maximum keypad size is not utilized the excess pins can be used as general purpose IOs. Three advanced PWM controllers in STMPE2401 STMPE2401 are designed to generate exciting lighting patterns.

Macina Voltage Regulator & Interface Marketing STOD1412 STOD1412 Voltage Regulator MONOLITHIC ACTIVE MATRIX OLED DISPLAY POWER SUPPLY Both switching regulators are provided with synchronous rectification which has the two-fold advantage of allowing higher application efficiency and of reducing to a minimum the external component count. STOD1412 STOD1412's outputs are able to deliver a current in excess of 120mA. A full set of control and protection features such as soft-start, inrush current control, short circuit and thermal shutdown are integrated. STOD1412 STOD1412 Additional Features Active Matrix Organic Light Emitting Diode (AM-OLED) displays are becoming more common in portable applications such as mobile phones, digital still cameras, MP3 players, PMP and handheld gaming devices. Their expansion is primarily due to the technological advantages over traditional LCDs. An OLED display is basically an emissive layer made by an organic compound between two conductors. Unlike the well known LCD displays, this technology does not require any backlight architecture. This easily translates into a thinner design profile and a significantly lower power consumption. The additional advantages of a wide viewing angle and bright full-colors make OLEDs the best choice in most of today's portable applications. Simple And Efficient Powering Powering OLED displays is not entirely straightforward; two regulated voltage rails have to be provided, and as with all battery operated devices the electrical efficiency must be maximized. To address the power needs of AM-OLED displays ST has introduced the STOD1412 STOD1412, a single-chip solution for compact and efficient powering of AM-OLED displays in a tiny QFN package. Its excellent static and dynamic performance makes it unquestionably the best choice for designers. Operating input voltage range from 2.7 to 5.5V True shutdown Efficiency: 80% from 10 to 30mA, 85 from 30 to 120mA (output current) Low quiescent current (
