Diodes Incorporated 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.

These automotive latches are lead, halogen, antimony free, fully RoHS compliant, and AEC-Q100 qualified. Typical applications include industrial motors, white goods, pumps, rotation speed and direction detection, linear speed and direction detection, and angular position detection.
