General Description:
WSH416 is designed to integrate Hall sensor with complementary output drivers and frequency generator together on the same chip, it is suitable for high speed and large DC brushless motors. It includes a temperature compensated voltage regulator, a differential amplifier, a Hysteresis controller, two open-collector output drivers capable of sinking 1.0A current load . An on-chip protection diode is implemented to prevent reverse power fault. And built-in thermal lock protection and auto-restart function is suitable for super high speed fan. It can replace the function of lock protection and auto restart function. The power will be shutdown automatically at 125°C to prevent the coils be damaged and atuo-restart after cooling down.
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 1.0A for driving large load.
● Lower current change rate reduces the peak output voltages during switching.
● Available in rugged low profile SIP-4L packages.
● Built-in protection diode for reverse power supply fault.
● Built-in thermal protection and auto-restart function.
