PT2485 - H-Bridge Motor Driver

General Description

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.

Key Features

  • 8V to 45V Supply Voltage Range.
  • 5A Maximum Peak Output Current at VM=24V, 3.5A Continue Output Current with additional heatsink.
  • Low Conduction Resistance Switches: 0.2Ω(typ) for high side + low side in Tj=25℃.
  • Phase and Enable Control Logic Interface.
  • H-Bridge Output Current is determinate by 5 Bits, 32 Levels PWM Current Regulation Inputs.
  • Winding Current Decay Modes - Mixed Decay - Slow Decay - Fast Decay.
  • Drives a Single DC brushed Motor or Single Windi.

DESCRIPTION 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 5A maximum peak output current (VM=24 V, 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 motor current decay mode also programmable by a tristate input pin.
