WSH410 winson reserves the right to make changes to improve reliability or manufacturability. hall effect sensor ic with complementary output drivers and frequency generator 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 400ma for driving large load. lower current change rate reduces the peak output voltages during switching. available in rugged low profile sip-4l/sip-5l packages. built-in protection diode for reverse power supply fault. general description: WSH410 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 400ma current load. an on-chip protection diode is implemented to prevent reverse power fault. 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. WSH410 are rated for operation over temperature range from C 20 ? c to125 ? c and voltage ranges from 2.8v to 20v. name p/i/o pin# description vcc p positive power supply out1 o output pin #1 out2 o output pin #2 vss p ground ? winson semiconductor corp. 2005/8/121
