COM OCH147H Hall Effect Latched Sensor ◼ General Description The OCH147H is an integrated Hall effect latched sensor designed for electronic commutation of brush-less DC motor applications.
The device using HV BCD 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.
If a magnetic flux density larger than threshold Bop,output is turned on(low).
The output state is held until a magnetic flux density reversal falls below Brp causing OUT to be turned off(high).
◼ Features ⚫ Wide operating voltage range: 3.
3V~26V ⚫ Operating temperature range: -40°C ~+150°C ⚫ Temperature compensation ⚫ Reverse polarity protection ⚫ Open-Drain pre-driver ...
