L6219DSA
Stepper Motor Driver, Injection control-
Active
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.
