SLIS006 - D2942, JUNE 1987 - REVISED JANUARY 1990
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 high- current 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 pseudo- Darlington 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 high- impedance 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.
