L6219 DIP-24 Stepper Motor Driver IC

The L6219 DIP-24 Stepper Motor Driver IC is a bipolar motor driver designed for controlling bipolar stepper motors and can also be used for bidirectional control of two DC motors. It integrates dual full-bridge output stages along with current sensing, PWM current regulation, protection diodes, and thermal shutdown, reducing the number of external components required in a motor-control circuit.

The L6219 supports a motor supply voltage from 10V to 46V, while each output winding can handle up to 750mA continuous current and up to 1A peak startup current. The device supports half-step, full-step, and microstepping modes, making it suitable for different stepper motor control requirements.

The DIP version is a 24-pin through-hole package (PDIP/DIP-24). The device includes separate motor outputs, sense-resistor connections, comparator inputs, phase inputs, logic inputs, reference-voltage inputs, and ground connections. The logic supply is typically 4.75V to 5.25V, with logic HIGH recognized from approximately 2.4V and logic LOW up to 0.8V.

The L6219 is suitable for stepper motor controllers, automation equipment, robotics, positioning systems, CNC equipment, printers, industrial machinery, motion-control circuits, and electronic equipment repair. It can also be useful when replacing an L6219 in older or specialized equipment where the original DIP package is required.
