Full-Bridge Driver for DC Motors (driver for controlling the forward and reverse rotations)

The TA7291AP/TA7291AS (J)/TA7291AF is a full-bridge driver to

control the forward and reverse rotations. Each driver can select

one of four modes: CW, CCW, stop, brake.

The TA7291AP is designed to provide output currents of 1.0 A (typ.)

and 2.0 A (peak). The TA7291AS (J)/TA7291AF is designed to

provide output currents of 0.4 A (typ.) and 1.2 A (peak).

There are two different power supply pins for each driver: one on

the output side and the other on the control side of the driver. Also,

adjusting the voltage supplied to the motor.

The input circuit of the driver is compatible with CMOS logic

because it draws a small amount of input current.

Features

· Thermal shutdown and overcurrent protection

· Flyback diodes

· Hysteresis for all inputs

· Standby mode available
