BIPOLAR HALL EFFECT POSITION SENSOR 2007-1-24 1/5 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 temperat ure 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 z Maximum output sink current 50mA z Package: SIP3 „ PIN CONFIGURATION ( Top View) „ FUNCTIONAL BLOCK DIAGRAM „ ABSOLUTE MAXIMUM RATINGS Vcc Pin Voltage 20V Output OFF Voltage,Vce 30V Output ON Current(Io) (Continuous Current) 50mA Power Dissipation (Ta=25℃) 400mW Operating Temperature Range -40℃~+150℃ Storage Temperature Range -65℃~+150℃ Junction Temperature +150℃ Lead Temperature(Soldering,10 sec) +230℃ Name No. Status Description Vcc 1 P IC Power Supply Gnd 2 P IC Ground Output 3 O It is low state during the N magnetic field Vcc Gnd Output Sensor Regulator Vcc Output Gnd Hall
