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.
