OCH1440
Overview
The OCH1440 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 and integrated the pull-up resistor.
- Wide operating voltage range: 2.5V~20V
- Wide operating temperature range: -40°C ~+125°C
- Integrated pull-up resistor
- Package: SIP3 & SOT23-3L
