WSH42FB

www.DataSheet4U.com WSH42FB Single Coil Hall Effect IC with Thermal Lock Protection and Auto-Restart Features: Operate from 2.8V to 14V supply voltage. On-chip Hall sensor. Internal bandgap regulator allows temperature compensated operations and a wide operating voltage range. Output sinking capability up to 350mA for driving large load. Lower current change rate reduces the peak output voltages during switching. Available in rugged low profile SIP-4L,SIP-5L and SOT-25 packages. Built-in Frequency Generator. Built-in protection diode for reverse power supply fault. Prevent the fail situation during lock status or high temperature Built-in thermal lock protection and auto-restart function. General Description: www.DataSheet4U.com WSH42FB 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 implemented to prevent reverse power fault. It also includes coil parts. You can eliminate all the external components for the function of FG and reverse protection diode. And built-in thermal lock protection and auto-restart function will automatically shutdown power at 110°C t...
