OCH147
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.

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.
