General Description
Using BCD process, the AS1153 is designed for
high performance Omnipolar detection hall-effect
application, such as automotive, industrial, electric
tools, home appliances, rotor position sensing,
brushless DC motor etc. The hall IC integrated an
on-chip hall voltage generator for magnetic sensing, a
comparator that amplifiers the hall voltage, hall sensor
with dynamic offset cancellation system, an pull-up
resistance, and a Schmitt trigger to provide switching
hysteresis for noise rejection, and a voltage regulator
for operation with supply voltage of 2.7V to 40V.
