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 isdesigned

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 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).

FUNCTION TABLE

INPUTS

OUTPUT

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.

H = high-level ,

X = irrelevant

Z = high-impedance (off)

L = low-level

External high-speed output-clamp diodes should be used for inductive transient suppression. To minimize

device power dissipation, a V

supply voltage, separate from V

, is provided for the logic inputs.

CC2

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.
