Overview
The STK681-352-E is a hybrid IC for use in current control forward/reverse DC motor driver with brush.
Applications
 Office photocopiers, printers, etc.
Features
Allows forward, reverse, and brake operations in accordance with the external input signal.
8A peak startup output current and 12A peak brake output current.
On-chip output short-circuit detection function.
Reduced voltage detection function (15V) for a motor supply voltage.
Connecting an external current detection resistor allows overcurrent detection and peak current control in the
PWMoperation mode.
Obviate the need to design for the dead time in order to turn off the upper- and lower drive devices when
switchingbetween the forward and reverse operation mode.
