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
Package: SOT23-3L

Note: CIN is for power stabilization and to strengthen the noise immunity, the recommended capacitance is 0.1~1uF.
If the VCC power supply is clean, the CIN can be cancelled.
