TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic

TA7288P

Sequential Dual-Bridge Driver (Driver for Switching between Forward and Reverse

Rotation) for DC Motor

The TA7288P is a bridge driver that is ideal for normal / reverse

switching.

This circuit offers four modes: normal rotation, reverse rotation,

stop, and brake.

The output current is 1.0 A (AVE.) and 2.0 A (PEAK). TA7288P

has an ideal circuit configuration for VCR front tape loading and

offers two types of power supply pins. One is for output, the other

motor voltage facilitates motor voltage adjustment. The IC

requires little input current, enabling direct connection with

CMOS.

Features

Output current up to 1.0 A (AVE.) and 2.0 A (PEAK)

Built-in thermal shutdown circuit and overcurrent protection circuit for output pins

Built-in punch−through current restriction circuit

Built-in back electromotive force absorber diode

Built-in hysteresis circuit

Weight: 2.47 g (typ.)
