MOTOR CONTROL DRIVER CHIP

DESCRIPTION

The ASIC device UTC MD9110 motror controller and driver is

designed with two-channel push-pull power amplifier discrete

circuits integrated into a monolithic IC, and peripheral devices

reduce the cost, improve the reliability of all. This chip has two

TTL / CMOS compatible output, with high reliability; Two output

terminals can directly drive the motor forward or reverse. It has a

large current driving capability, each channel through 750~

800mA of continuous current, peak current capability up to

1.5~2.0A, and it has a low output saturation voltage; built-in

clamp diode which can release the reverse current of the

inductive load. UTC MD9110 is widely used in toy car motor,

stepper motor or switching power tube.
