L6219 Dual H-Bridge Stepper Motor Driver IC 46V 1.4A DIP-24
The L6219 is a monolithic dual full-bridge (dual H-bridge) motor driver IC from STMicroelectronics, designed to drive the two windings of a bipolar stepper motor or two independent brushed DC motors. Each bridge delivers up to 1.4A from a single supply of up to 46V, and the logic inputs are TTL-compatible for direct interfacing with 5V microcontrollers and control logic. Bridge current can be regulated externally via PWM/chopper control, allowing precise phase-current setting in stepper applications. On-chip thermal shutdown protects the device against overtemperature, and the through-hole DIP-24 package makes it easy to use on breadboards, prototyping boards, and socketed repair work — a popular replacement part for classic printer, plotter, and industrial motion-control boards.
