COM OCH147 Bipolar Hall Effect Position Sensor ◼ General Description The OCH147 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 integrated the pull-up resistor.
An internal bandgap regulator is used to provide temperature compensated supply voltage for internal circuits and allows a wide operating supply range.
To minimize the BOM cost, only one external component is needed to complete the application circuit.
◼ Features ⚫ Wide operating voltage range: 3.
8V~30V ⚫ Wide operating temperature range: -40°C ~+125°C ⚫ Reverse polarity protection ⚫ Integrated pull-up resistor ⚫ Package: SOT23-3L ◼ Applications ⚫ Rotor Position Sensing ⚫ Brush-less DC Fan ⚫ Brush-less DC Motor ⚫ Spe...
