Low-voltage Hall latches from enable high-sensitivity sensing

Diodes Incorporated has released a series of automotive-compliant, low-voltage, high-sensitivity Hall-effect latches. Devices in the AH171xQ series are developed for BLDC motor commutation speed measurement, angular or linear encoders, and position sensors in demanding automotive and industrial applications.

Device options in this series offer a selection of three high-sensitivity BOP and BRP settings (+/-7Gauss, +/-18Gauss, and +/-50Gauss) with tight operating windows to supply accurate and reliable switching points. These latches have a fast 30kHz sensing bandwidth to support higher rotational speed-sensing, while their high levels of protection against ESD, 8kV HBM, and 2kV CDM ensure robust operation.

These AEC-Q100 Grade 0 qualified latches, which provide a chopper-stabilised architecture and an internal regulator with temperature compensation, have been optimised to operate reliably across the 2.4V to 5.5V supply range and the entire -40C to +150C temperature range. They are manufactured in IATF 16949 certified facilities and support PPAP documentation.
