Part Name(s) : L6219DSA E-L6219DSA E-L6219DSATR ST-Microelectronics
STMicroelectronics
Description : STEPPER MOTOR DRIVER FOR AUTOMOTIVE RANGE

Description
The L6219DSA is a bipolar monolithic integrated circuits intended to control and drive both winding of a bipolar STEPPER MOTOR or bidirectionally control two DC MOTORs.
The L6219DSA with a few external components FORm a complete control and drive circuit FOR LS TTL or microprocessor controlled STEPPER MOTOR system. The power stage is a dual full bridge capable of sustaining 46 V and including four diodes FOR current recirculation.
A cross conduction protection is provided to avoid simultaneous cross conduction during switching current direction.
An internal pulse-width-modulation (PWM) controls the output current to 750 mA with peak startup current up to 1 A.
Wide RANGE of current control from 750 mA (each bridge) is permitted by means of two logic inputs and an external voltage reference. A phase input to each bridge determines the load current direction. A thermal protection circuitry disables the outputs if the chip temperature exceeds safe operating limits.

Features
■ Able to drive both windings of bipolar STEPPER MOTOR
■ Output current up to 750 mA each winding
■ Wide voltage RANGE: 10 V to 46 V
■ Half-step, full-step and microstepping mode
■ Built-in protection diodes
■ Internal PWM current control
■ Low output saturation voltage
■ Designed FOR unstabilized MOTOR supply voltage

Description : Bipolar STEPPER and High Current DC MOTOR DRIVER

Description
The A3989 is designed operate at voltages up to 36 V while driving one bipolar STEPPER MOTOR, at currents up to 1.2A, and one DC MOTOR, at currents up to 2.4 A.
