Diodes Incorporated AH396x Dual Hall Effect Latch Sensors are high voltage sensors designed for applications that require accurate speed and direction sensing. The design is optimized to operate over a 2.7V to 27V supply range to support a wide range of demanding applications. With a chopper-stabilized architecture and an internal bandgap regulator to provide a temperature-compensated supply for internal circuits, the AH3965/AH3966/AH3967 sensors offer speed and direction outputs. In contrast, the AH3968 provides two independent outputs at Q1 and Q2. The devices feature a reverse-blocking diode with a Zener clamp on the supply for robustness and protection.
