STK681-320

Ordering number : ENA0762A STK681-320 Thick-Film Hybrid IC Forward/Reverse Motor Driver http://onsemi.com Overview The STK681-320 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. 5.2A startup output current and 8A peak brake output current. Incorporating a current detection resistor (0.056Ω), fixed current control is possible. Obviate the need to design for the dead time in order to turn off the upper- and lower drive devices when switching between the forward and reverse operation mode.
