UNISONIC TECHNOLOGIES CO., LTD L6219 LINEAR INTEGRATED CIRCUIT DUAL FULL-BRIDGE PWM MOTOR DRIVER  DESCRIPTION The L6219 motor driver is designed to drive both windings of a bipolar stepper motor or bidirectionally control two dc motors. Both bridges are capable of sustaining 45V and include internal pulse-width modulation (PWM) control of the output current to 750mA .The outputs have been optimized for a low output saturation voltage drop (less than 1.8V total source plus sink at 500mA ). .

Stepper motor driver

L6219R Stepper motor driver Features ■ Able to drive both windings of bipolar stepper motor ■ Output current up to 500 mA each winding ■ Wide voltage range 4.5 V to 10 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 ■ Internal thermal shutdown Description 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 10 V and including four diodes for current recirculation. SO-24 (20+2+2) 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 1 A. Wide range of current control from 500 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. Table 1.
