Overview

February 1999 PBL 3770A High Performance Stepper Motor Drive Circuit Description 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.
The circuit is pin-compatible with the PBL 3717 industry-standard driver.
Two PBL 3770A and a small number of external components form a complete control and drive unit for LS-TTL or microprocessor-contro...
