TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC

TA7289P,TA7289F/FG

PWM STEPPING MOTOR DRIVER

The TA7289P, TA7289F/FG are PWM solenoid driver designed

especially for use high efficiency stepping motor control.

It consist of 1.5A peak current drive capable output full bridge

driver, oscillation circuit for PWM switching, 4bit D−A for output

current control and TTL compatible input circuit.
