Brushed DC/Solenoid Drivers


PT2485

The PT2485 is a monolith integrated motor driver designed for printers, scanners, and home and office automated equipment. The single H-bridge drivers can drives a DC brushed motor or single winding of a bipolar stepping motor. The output H-bridge driver is consists by all of N-channel MOSFET, and allows driving up to 5-Amps maximum peak output current (VM=24V, Ta=25°C).

The phase and enable, industrial standard control logic interface is very versatile to configuring the H-bridge output switches with 32 levels PWM current regulation, it is useful to limiting the starting current of the DC brushed motor; or determinate the winding current of a stepping motor. The PWM current regulates by slow decay mode.

The PT2485 is available in a 28-pin HTSSOP package with thermal pad.
