TPIC0298 Dual Full-H Driver

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).

Features

r 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.
