Specifications:

• 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 stepper motor system. The power stage is a dual full bridge capable of sustaining 46 V 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 750 mA with peak startup current up to 1 A.
• Wide range of current control from 750 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.

Features:

• Able to drive both windings of bipolar stepper motor
• Output current up to 750 mA each winding
