Stepping Motor Driver IC 


PT2483L

The PT2483L is a monolithic integrated motor driver designed for printer, scanner or home appliance. The built-in two channel H-bridges designs for driving a bipolar stepping motor or two DC-brushed motors.

The H-bridge driver is consists by all of N-channel MOSFET allows delivering up to 2.5A maximum output current (VM=24 V, Ta=25°C).

The Phase/Enable input interface is a common configuration for the motor driver; it is very versatile to control the H-bridge switches to determinate motor winding current and phase. The motor current decay mode is programmable by a tri-states input pin.

The PT2483L is available in a 28-pin HTSSOP package with thermal pad
