The STMicroelectronics L6219 is a bipolar monolithic integrated circuit designed to control and drive both windings of a bipolar stepper motor. With a few external components, it forms a complete control and drive circuit for microprocessor-controlled stepper motor systems.
Key electrical specifications include an output current of up to 750 mA per winding and a wide voltage range from 10 V to 46 V. The device features internal PWM current control, capable of handling peak startup currents up to 1 A. It supports half-step, full-step, and microstepping modes, providing flexibility in motor control.
Designed for unstabilized motor supply voltage, the L6219 includes built-in protection diodes and internal thermal shutdown for enhanced reliability. The power stage is a dual full bridge capable of sustaining 46V and includes four diodes for current recirculation. A cross-conduction protection is provided to prevent simultaneous cross-conduction during switching current direction.
This IC is available in a 24-SOIC surface mount package, making it suitable for various electronic designs. The operating temperature range is -20°C to 150°C (TJ).
