WSH277 - Winson

WSH277 Hall Effect Sensor IC

W277 is designed to integrate Hall sensor with complementary output drivers and frequency generator together on the same chip, it is suitable for speed measurement, revolution counting, positioning, and DC brushless motors. It includes a temperature compensated voltage regulator, a differential amplifier, a Hysteresis controller, two open-collector output d.

Features

z Operate from 2.8V to 24V supply voltage. z On-chip Hall sensor. z Internal bandgap regulator allows temperature compensated operations and a wide operating voltage range. z High output sinking capability up to 500mA for driving large load. z Lower current change rate reduces the peak output voltages during switching. z Available in rugged low profile SIP-4L packages. z Built-in protection diode for reverse power supply fault. z Built-in thermal lock protection and auto-restart function. General Description: W277 is designed to integrate Hall sensor with complementary output drivers and freq.
