PBL 3770A is a bipolar monolithic circuit intended to control and drive the current in one winding of a stepper motor.

It is a high power version of PBL 3717 and special care has been taken to optimize the power handling capability without suffering in reliability.

The circuit consists of a LS-TTL compatible logic input stage, a current sensor, a monostable multivibrator and a high power H-bridge output stage.
