Low-voltage Hall latches enable high-sensitivity sensing

Diodes has released a series of automotive-compliant, low-voltage, high-sensitivity Hall-effect latches.

Devices in the AH171xQ series are designed for brushless DC (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 choice of three high-sensitivity BOP and BRP settings (+/-7Gauss, +/-18Gauss, and +/-50Gauss) with tight operating windows to provide 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 electrostatic discharge (ESD), 8kV human body model (HBM), and 2kV charge device model (CDM) ensure robust operation.

These AEC-Q100 Grade 0 qualified latches, which feature 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 -40 to +150°C temperature range. They are manufactured in IATF 16949 certified facilities and support PPAP documentation.
