Product Overview
The AH1711Q/AH1712Q/AH1713Q/AH1714Q is an AEC-Q100 qualified low-voltage, high-sensitivity Hall effect latch IC designed for automotive applications such as brushless DC-motor commutation, speed measurement, and position sensing. Optimized for a 2.4V to 5.5V operating range, it features a chopper-stabilized architecture and internal bandgap regulator for reliable performance across the operating temperature range. The open-drain output switches based on magnetic field polarity and strength, latching until the field reverses. It offers superior temperature stability, minimal switch point drift, and enhanced immunity to stress.
