PT2479L - Dual H-Bridge Motor Driver

General Description

The PT2479L is a monolith integrated motor driver designed for printers, scanners or home appliance.

The built-in two channel H-bridges designs for driving a bipolar stepping motor or two DC-brushed motors.

Key Features

  • 8V to 40V maximum supply voltage.
  • 2.5A maximum driving current at VM=24V (with additional heatsink).

PRELIMINARY PT2479L 40V/2.5A, Dual H-Bridge Motor Driver DESCRIPTION The PT2479L is a monolith integrated motor driver designed for printers, scanners 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 driving up to 2.5A maximum output current (VM=24 V, Ta=25°C). The dual-input interface is a common configuration for the motor driver; it is very versatile to control the Hbridge switches to determinate motor winding current and phase. The motor current decay mode is programmable by a tri-states input pin. The PT2479L is available in a 28-pin HTSSOP package with thermal pad.
