AH396xQ Automotive Dual Hall Effect Latches Diodes Incorporated AH396xQ Automotive Dual Hall Effect Latches are high voltage sensors designed with accurate speed and direction sensing. These dual hall latches provide a temperature-compensated supply for internal circuits with chopper-stabilized architecture and an internal bandgap regulator. The AH396xQ latches operate from a 2.7V to 27V supply voltage range and -40°C to 150°C of temperature range. These latches offer Battery polarity reverse connection protection, transient spike voltage protection, and UVLO protection. The AH3965/AH3966/AH3967 latches provide speed and direction outputs, while the AH3968 provides two independent outputs.
