Product details

Description

www.DataSheet4U.com WSH420 is designed to integrate Hall sensor with two push-pull output drivers and frequency generator together on the same chip, it is suitable for single coil DC brushless motors.It includes a temperature compensated voltage regulator, a differential amplifier, a Hysteresis controller, complementary bi-direction drivers for sinking and driving large current load and an open-collector frequency generator capable of sinking 10mA current load.An on-chip protection diode is

Features

Operate from 2.4V to 8V supply voltage. On-chip Hall sensor. Internal bandgap regulator allows temperature compensated operations and a wide operating voltage range. Output sinking capability up to 450mA for driving large load. Lower current change rate reduces the peak output voltages during switching. Available in rugged low profile SIP-4L, SOT-25 packages. Built-in Frequency Generator. Built-in protection resistance for reverse power supply fault. Prevent the fail situation during lock statu.
