Stepping Motor Driver IC


PT2469

The PT2469 is a monolith integrated motor driver designed for printers, scanners, and home and office automated equipment. The two H-bridge drivers can drive a bipolar stepper motor or two DC motors. The output H-bridge driver is consists by all of N-channel MOSFET. The PT2469 is allows driving up to 1.6A maximum output current (VM=24 V, Ta=25°C).

An EN-PH type parallel logic control interface can be configuring the output switches ON-OFF of H-bridge, and motor current decay mode is also programming by the parallel input port.

The PT2469 is available in a 28-pin HTSSOP package with thermal pad and in a 28-pin QFN package thermal pad.
