OCH41N

WWW.ORIENT-CHIP.COM OCH41N Bipolar Latch Hall Effect Sensor ◼ General Description The OCH41N 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 trigger 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 South pole of sufficient strength will turn the output ON. In the absence of a magnetic field, the output is OFF. ◼ Features ⚫ Wide operating voltage range: 3.8V~30V ⚫ Open-Collector Output ⚫ Reverse polarity protection ⚫ Maximum output sink current 25mA ⚫ Package: SIP3 ◼ Pin Configuration (Top View) 3 Output 2 Gnd 1 Vcc Name No. Status Description Vcc 1 P IC Power Supply Gnd 2 P I...
