General
Description
Using
bipolar process, the AS1700 is designed for high performance unipolar detection hall-effect application, such as E-bike, E-Motorcycle, 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 3.8V
to 60V.
AS1700 is designed to respond to South pole. 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.
