WSH41S is designed to integrate Hall sensor with complementary output drivers and speed control function together on one chip, it is suitable for speed measurement, revolution counting, positioning, and DC brushless motors.
Features
Operate from 2.8V to 20V supply voltage. On-chip Hall sensor. Internal bandgap regulator allows temperature compensated operations and a wide operating voltage range. High output sinking capability up to 600mA for driving large load. Lower current change rate reduces the peak output voltages during switching. Available in rugged low profile SOT-25 packages. PS pin can accept PWM signal to program rotation speed. Built-in protection diode for reverse power supply fault. Built-in thermal lock pro.
