L6219

L6219 LINEAR INTEGRATED CIRCUIT STEPPER MOTOR DRIVER DESCRIPTION The L6219 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 L6219 with a few external components form a complete control and drive circuit for LS-TTL or microprocessor controlled SOP-24-375-1.27 stepper motor system. The power stage is a dual full bridge capable of sustaining 46V and including four diodes for current ORDERING INFORMATION recirculation. A cross conduction protection is provided to avoid simultaneous cross conduction during switching current direction. Device Package L6219 SOP-24-375-1.27 An internal pulse-width-modulation (PWM) controls the output current to 750mA with peak start-up current up to 1A. Wide range of current control from 750mA (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.
