Product Overview
STK681-320: Motor Driver, DC, Forward / Reverse, with Brush
For complete documentation, see the data sheet.
STK681-320 is a forward/reverse motor driver thick film hybrid IC. It is designed for current control of DC brush motors. It allows
forward, reverse, and brake operations in accordance with the external input signal. The peak startup output current is 5.2A and the
peak brake output current is 8A. It have current sensing resistor built-in, and we can space-saving design easily. And it 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.
Features Benefits
Built-in current sensing resistor Fixed current control is possible
Built-in over-heat protection Suppresses current drain when overheating state occurs
Built-in over-current protection The 50µs off time self-excitation chopping function
No need for dead time design Easy to safety design
Applications End Products
Computing & Peripherals Multi-Function Printer
Industrial Slot machine
Vending Machine
