Diodes Incorporated AH397xQ Automotive Dual Hall Effect Latches are high voltage sensors designed with accurate speed and direction sensing. The AH397xQ latches are integrated with self-diagnostics which monitor internal blocks, and they will enter safe mode when an error is detected. 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 AH3975Q/AH3976Q/AH3977Q latches provide speed and direction outputs, while the AH3978Q provides two independent outputs.
