PT2483L
PT2483L is Dual H-Bridge Motor Driver manufactured by Princeton Technology.
PRELIMINARY PT2483L 40V/2.5A, Dual H-Bridge Motor Driver
DESCRIPTION
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 mon 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
