  • The L6219R 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 L6219R 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 10V 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 500mA with peak start-up current up to 1A. Wide range of current control from 500mA (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.

    主要特性

    • Low output saturation voltage
    • Internal pwm current control
    • Internal thermal shutdown
    • Able to drive both windings of bipolar stepper motor
    • Wide voltage range 4.5V to 10V
    • Output current up to 500mA each winding
    • Built-in protection diodes
    • Designed for unstabilized motor supply voltage
    • HAlf-step, full-step and microstepp-ing mode
