SMS64EV
SMS64EVAL fully functional evaluation board designed demonstrate features SMS64 Nonvolatile, Programmable Supply Monitor Sequence Controller. EVAL board manages four unique input voltage levels voltage Several key, user-configurable functions are: Power on/off sequence management User-Programmable Voltage Sensor with UnderVoltage Over-Voltage (UV/OV) fault monitoring (20mV increments) Programmable IRQ#, RSTA# RSTB# outputs Programmable RSTA# RSTB# time-out periods Programmable Watchdog/Longdog timers levels derived on-board ranging from 0.9V 5.5V; deriving power from highest input (2.7V). Unlike similar products; SMS64 features on-board nonvolatile memory, making truly `UserProgrammable'. Additional features included EVAL board: User-Programmable interface digitally control analog supervisory functions. visual indicators Master Reset (MR#) WLDI momentary pushbuttons. EZ-connect power, signal pins modular power connectors. SMS64 48-pin TQFP spring-loaded socket convenient prototyping evaluation.

Operating Instructions
TEST EQUIPMENT REQUIRED Personal Computer with either Windows 2000, parallel port. Power Supply, 2.7V-5.5V, 10mA (full evaluation requires unique voltages). Oscilloscope, Digital sampling, 4-channel TEST STEPS Software setup Close open Windows application programs. Insert "SMS64EV Software" into CD-ROM drive. Follow installation instructions, rebooting computer prompted. After computer reboots, perform full power shutdown install Dongle. Hardware setup Dongle Installation Remove existing cabling from computer's parallel port (LPT1). Connect Dongle parallel port. Plug Interface cable into Dongle. Insert Dongle cable onto SMS64 Evaluation board (pin connector board corresponds white wire with orange stripes). Reapply power computer.

Figure SMS64 Default Programmer Window with Default Data Loaded into Configuration Registers Evaluation Board Layout SMS64 highly programmable six-channel voltage sequencer monitor. contains outputs which individually programmed either active-high open-drain, active-low open drain, active high voltage. With this flexibility, SMS64 used with many different board configurations. Since SMS64 evaluation board shows only those possibilities, there limited number configurations SMS64 which used with evaluation board. purpose understanding operation SMS64 evaluation board layout configuration will discussed. SMS64 Evaluation Board EZ-connector connect four supply voltages board. These supply inputs mark 5.0VI, 3.3VI, 2.5VI, 1.8VI connected pins VCCA through VCCD SMS64, respectively.

PWR_EN connected switch hardware control power-on/power-off sequencing. SMS64 Default Configuration default configuration settings SMS64 viewed clicking Load Defaults button GUI. This will load with default configuration part allow user view these settings. Each channel under-voltage detection with voltage thresholds nominal voltage. Channels selected "wait VCC" channels meaning that inputs these channels must higher than their under-voltage threshold before power-on sequence allowed. Channels selected "wait VCC" channels ensure that input side FET's supplied before sequencing begins. also important have channels configured this that LDO's have power before they sequenced outputs channels provide high voltage their active state drive FET's. outputs channels open-drain active-high accordance with requirements LDO's. "wait VCC" settings output level settings should changed from default settings when used with SMS64EV evaluation board they specific board configuration.

Channels trigger RSTA# undervoltage channels trigger RSTB# under-voltage. addition RSTA# cleared during power-on sequence PUPD going active. default configuration settings disable "off" sensors SMS64. these sensors tell SMS64 when inputs below 0.8V. This used sequence down supplies disabled because there early voltage 5.0VO node preventing from dropping below 0.8V. MIC49150 Configuration MIC49150 capable regulating 0.9V. channel used sequence monitor MIC49150 uses different setting monitor input because output voltage from MIC49150 fall below 0.9V minimum monitor voltage SMS64. Therefore, channel monitor input "Use Naked Input'. SMS64 Default Micrel file CDROM contains this setting should used MIC49150 populated. Power-On Power-Off SMS64 triggered power-on sequence power-off sequence from either PWR_EN switch evaluation board. PWR_UPDN SMS64 edge-triggered pin. rising edge this triggers power-on sequence while falling edge triggers power-off sequence. Once power-on power-off command issued (either action PWR_UPDN pin) SMS64 will ignore other commands until that sequence complete. Note: Switch noise PWR_EN switch cause SMS64 power-on power-off from wrong edge toggled switch.
