TOSHIBA BiCD Integrated Circuit Silicon Monolithic

TB67H481FTG

BiCD Constant Current Dual H-bridge Driver IC

1. Description

TB67H481FTG is a Dual H-bridge driver IC for driving 2 brushed

motors / 1 stepping motor.

Fabricated with the BiCD process, output rating is 50 V/3.0 A.

The built-in regulator for IC operation allows the motor to be driven

by a single VM power supply.
