原裝供應(yīng) PT2483L 普誠雙H橋電機(jī)驅(qū)動器

DESCRIPTION

The PT2483L is a monolithic integrated motor driverdesigned for printer, scanner or home appliance. Thebuilt-in two channel H-bridges designs for driving abipolar stepping motor or two DC-brushed motors.The H-bridge driver is consists by all of N-channelMOSFET allows delivering up to 2.5A maximum outputcurrent (VM=24 V, Ta=25°C).

The Phase/Enable input interface is a commonconfiguration for the motor driver; it is very versatile tocontrol the H-bridge switches to determinate motorwinding current and phase. The motor current decaymode is programmable by a tri-states input pin.

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