General
Description
Using
bipolar process, the AS1601 is designed for high performance latch detection hall effect application, such as E-bike, 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, an open collector output, and a Schmitt trigger to provide switching hysteresis for noise rejection, and a voltage regulator for
operation with supply voltage of 3.5V to 60V.
The
integrated filter and protection block can keep the output voltage at safety level and avoid the damage of
the sensors.
AC1601 is designed to respond to alternating North and
South poles. White the magnetic flux density (B) is larger than operate point (BOP), the output will be turned on (low), the output is held until the magnetic flux density (B) is lower than release point (BRP), then turn
off (high).
The device is available in SIP-3L Package and is rated over the -40°C to 150°C. the package is RoHS compliant.
