Low voltage, high sensitivity Hall latches are automotive-compliant
Diodes has introduced the AH171xQ series of automotive-compliant, low voltage, high sensitivity Hall-effect latches. They are designed for brushless DC (BLDC) motor commutation speed measurement, angular or linear encoders and position sensors in demanding automotive and industrial applications.
The latches are available in 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, said Diodes. These latches have a fast 30kHz sensing bandwidth to support higher rotational speed-sensing, and high levels of protection against electrostatic discharge (ESD), 8kV human body model (HBM), and 2kV charge device model (CDM) for robust operation.
The AEC-Q100 Grade 0-qualified latches have a chopper-stabilised architecture and an internal regulator with temperature compensation. They have been optimised to operate reliably across the 2.4V to 5.5V supply range and a wide operating temperature range of -40 to +150 degrees C. The latches are available in SOT23 packages and manufactured in IATF 16949 certified facilities and support PPAP documentation.
Diodes provides semiconductor products to companies around the world operating in the automotive, industrial, computing, consumer electronics and communications markets. The product portfolio consists of discrete, analogue and mixed signal products and packaging technology, with application-specific solutions. The company has worldwide operations of 32 sites, including engineering, testing, manufacturing, and customer service.
