STMicroelectronics L6219R Stepper Motor Driver Datasheet
The L6219R is a bipolar monolithic integrated circuit designed to control and drive both windings of a bipolar stepper motor or bidirectionally control two DC motors. It is intended for use in LS-TTL or microprocessor-controlled stepper motor systems. The device includes a dual full-bridge power stage capable of sustaining 10 V, along with built-in protection diodes for current recirculation.
Key features include internal pulse-width-modulation (PWM) current control, half-step and full-step modes, and microstepping capability. The chip incorporates cross-conduction protection, thermal shutdown circuitry, and is designed for operation with unstabilized motor supply voltages ranging from 4.5 V to 10 V.
