OCH1443

OCH1443 60V High Voltage Unipolar Hall Effect Position Sensor ◼ General Description The OCH1443 is an integrated Hall effect sensor designed for electronic commutation of brush-less high-voltage high-power 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 an 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. ◼ Features ⚫ Wide operating voltage range: 3.8V~60V ⚫ ESD:HBM-8KV ⚫ Wide operating temperature range: -40°C~+150°C ⚫ Robust open-collector output ⚫ Package: SIP-3L(TO92S) ◼ Applications ⚫ High power Differential motor ⚫ High power electrombile motor ⚫ High power Brush less dc motor ⚫ High power Auto-motive transmission position ⚫ Speed and RPM (revolutions pe...
