SLIS006 - D2942, JUNE 1987 - REVISED JANUARY 1990
Formerly TLP298 2-A Output Current Capability Per Full-H Driver Applications Include Half-H and Full-H Solenoid Drivers and Motor Drivers Wide Range of Output Supply Voltage 5 V to 46 V Separate Input-Logic Supply Voltage Thermal Shutdown Internal Electrostatic Discharge Protection High Noise Immunity 3-State Outputs Minimized Power Dissipation Sink / Source Interlock Circuitry Prevents Simultaneous Conduction Improved Functional Replacement for the SGS L298 The TPIC0298 is a dual high-current full-H driver designed to provide bidirectional drive currents of up to 2 A at voltages from 5 V to 46 V. It is designed to drive inductive loads such as relays, solenoids, dc motors, stepping motors, and other highcurrent or high-voltage loads in positive-supply applications. All inputs are TTL compatible. Each output (Y) is a complete totem-pole drive with a Darlington transistor sink and a pseudoDarlington source. Each full-H driver is enabled separately. Outputs 1Y1 and 1Y2 are enabled by 1EN and outputs 2Y1 and 2Y2 are enabled by 2EN. When an EN input is high, the associated channels are active. When an EN input is low, the associated channels are off (i.e., in the highimpedance state). Each half of the device forms a full-H reversible driver suitable for solenoid or motor applications. The current in each full-H driver can be monitored by connecting a resistor between the sense output terminal 1E and GND and another resistor between sense output terminal 2E and GND.

External high-speed output-clamp diodes should be used for inductive transient suppression. To minimize device power dissipation, a VCC1 supply voltage, separate from VCC2, is provided for the logic inputs. The TPIC0298 is designed for operation from 0°C to 70°C.
PRODUCTION DATA information is current as of publication date. Products conform to specifications per the terms of Texas Instruments standard warranty. Production processing does not necessarily include testing of all parameters.

absolute maximum ratings over operating temperature range (unless otherwise noted)
NOTES: 1. All voltage values are with respect to the network GND, unless otherwise noted. 2. The maximum current limitation at this terminal generally occurs at a voltage of lower magnitude than the voltage limit. Neither the maximum current nor the maximum voltage for this terminal should be exceeded. 3. Combined output current applies to each of the two full-H drivers individually. This current is the sum of the currents at outputs 1Y1 and 1Y2 for full-H driver 1 and the sum of the currents at outputs 2Y1 and 2Y2 for full-H driver 2. The full-H drivers can carry the rated combined current simultaneously. 4. For operation above 25°C free-air temperature, derate linearly at the rate of 28.6 mW / °C. For operation above 75°C case temperature, derate linearly at the rate of 333 mW / °C. Due to variations in individual device electrical characteristics and thermal resistance, the built-in thermal overload protection may be activated at power levels slightly above or below the rated dissipation.
