L6219DSA数据手册集成电路（IC）的电机驱动器控制器规格书PDF

描述 Description

The L6219DSA is a bipolar monolithic integrated circuit intended to control and drive both windings of a bipolar stepper motor or bidirectionally control two DC motors.

With only a few external components, the L6219DSA controls and drives the circuit for LS-TTL or microprocessor-controlled stepper motor systems. The power stage is a dual full bridge sustaining 46 V and including four diodes for current recirculation.

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.

A wide range of current control from 750 mA (each bridge) is permitted by two logic inputs and an external voltage reference. A phase input to each bridge determines the load current direction. Thermal protection circuitry disables the outputs if the chip temperature exceeds safe operating limits.
