OCH277H
◼ General Description
◼ Features
The OCH277H is an integrated Hall sensor with
⚫ One-chip Solution (Hall Element + Driver)
output driver designed for electronic commutation of
⚫ Input Voltage Range : 3.3V to 20V
brushless DC motor applications. This IC is using HV
⚫ Reverse Supply Voltage Protection
BCD process internally includes an on-chip Hall sensor
⚫ For DC motor / Fan Systems
for magnetic sensing, an amplifier that amplifies the
⚫ Low Cost Solution
Hall voltage, a Schmitt trigger to provide switching
⚫ High Sensitivity Hall Sensor
hysteresis for noise rejection, a temperature compensation circuit to compensate the temperature drift of Hall sensitivity and two complementary
M open-Drain drivers for sinking large load current.
