OCH184

OCH184 Hall Effect Latched Sensor ◼ General Description The OCH184 is an integrated Hall effect latched sensor designed for electronic commutation of brush-less DC motor applications. The device using High Voltage process 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 an open-collector output. An internal band-gap regulator is used to provide temperature compensated supply voltage for internal circuits and allows a wide operating supply range. ◼ Features ⚫ Wide operating voltage range: 2.5V~26V ⚫ Operating temperature range: -40°C ~+125°C ⚫ Temperature compensation ⚫ Reverse polarity protection ⚫ Open-Drain pre-driver ⚫ Package: SIP-3L、SOT23-3L ◼ Applications ⚫ Rotor Position Sensing ⚫ Brush-less DC Motor ⚫ Speed measurement ⚫ Revolution counting W W W .ORIEN 1T- 2C 3HIP.COM ◼ Pin Configuration Name VDD GND...
