Formerly TLP298 Output Current Capability Full-H Driver Applications Include Half-H Full-H Solenoid Drivers Motor Drivers Wide Range Output Supply Voltage 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 L298 TPIC0298 dual high-current full-H driver designed provide bidirectional drive currents voltages from designed drive inductive loads such relays, solenoids, motors, stepping motors, other highcurrent high-voltage loads positive-supply applications. inputs compatible. Each output complete totem-pole drive with Darlington transistor sink pseudoDarlington source. Each full-H driver enabled separately. Outputs enabled outputs enabled 2EN. When input high, associated channels active. When input low, associated channels (i.e., highimpedance state). Each half device forms full-H reversible driver suitable solenoid motor applications. current each full-H driver monitored connecting resistor between sense output terminal another resistor between sense output terminal GND.
