PT2485
PT2485 is H-Bridge Motor Driver manufactured by Princeton Technology.
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.
The PT2485 is available in a 28-pin HTSSOP package with thermal pad.
