WSH277
Hall Effect Sensor IC with Thermal Lock Protection
and Auto Restart Function
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
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 drivers capable of sinking 500mA 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 120°C to prevent the coils be damaged and atuo-restart
after cooling down.
The temperature-dependent bias increases the supply voltage of the hall plates and
adjusts the switching points to the decreasing induction of magnets at higher
temperatures. Subsequently, the open collector output switches to the appropriate state.
W277 are rated for operation over temperature range from –20˚ C to 85˚C and voltage
ranges from 2.8V to 24V.
