FSH41

BIPOLAR HALL EFFECT POSITION SENSOR FSH41 „ GENERAL DESCRIPTION The FSH41 is an integrated Hall effect latched sensor designed for electronic commutation of brush-less DC motor applications. The device includes an on-chip Hall voltage generator for magnetic sensing, a comparator that amplifiers the Hall voltage, and a Schmitt to provide switching hysteresis for noise rejection, and open-collector output. An internal bandgap regulator is used to provide temperature compensated supply voltage for internal circuits and allows a wide operating supply range. A north pole of sufficient strength will turn the output ON. In the absence of a magnetic field, the output is OFF. „ FEATURES z Wide operating voltage range: 3.0V~20V www.DataSheet4U.com z Maximum output sink current 50mA z Package: SIP3 „ PIN CONFIGURATION (Top View) 3 2 1 Output Gnd Vcc Name Vcc Gnd Output No. 1 2 3 Status P P O Description IC Power Supply IC Ground It is low state during the N magnetic field „ FUNCTIONAL BLOCK DIAGRAM Vcc 1 Regulator Hall Sensor 3 Output 2 Gnd „ ABSOLUTE MAXIMUM RATINGS 20V 30V 50mA 400mW -40℃~+150℃ -65℃~+150℃ +150℃ +230℃ Vcc Pin Voltage Output OFF Voltage,Vce Output ON Current(Io) (Continuous Current) Power Dissipation (Ta=25℃) Operating Temperature Range Storage Temperature Range Junction Temperature Lead Temperature(Soldering,10 sec) 1/5 2007-1-24 BIPOLAR HALL EFFECT POSITION SENSOR FSH41 „ DC ELECTRICAL CHARACTERISTICS Symbol Vcc Vcc Min.
