STK681-360-E
Thick-Film Hybrid IC
Forward/Reverse Motor Driver
http://onsemi.com
Overview
The STK681-360-E is a hybrid IC for use in PWM 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 PWM signal.
5.8A peak startup output current and 8A peak brake output current.
Built-in current detection resistor (0.05Ω : resistor tolerance 2%) and supports constant-current control.
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.

* The state IN1 = IN2 = high, PWM = L is illegal during motor operation.
* PWM pin (14pin) is active Low.
Notes
(1)The value of the power supply bypass capacitor C1 must be set so that the capacitor ripple current, which changes
with the motor current, remains within the allowable range.
(2) While the Vref2 pin is normally handled by being left open, note that the thermal protection circuit will no longer
operate if this pin is connected to ground or the P.S pin.
(3) Current is controlled by a constant-current chopping operation by transistors F1 and F2. The timing for the OUT1 or
OUT2 output voltage and the F1 or F2 drain current is shown below.
(4) Do not connect or wire any of the NC (unused) pins that appear in either the block diagram or the application circuit
examples to the circuit pattern on the PCB.
