description
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 V_CC1 supply voltage, separate from V_CC2, is provided for the logic inputs.
The TPIC0298 is designed for operation from 0°C to 70°C.
