High-Sensitivity Hall Effect Latches | AH171xQ Series by Diodes

August 2, 2023 — Diodes Corporation, a leader in electronic component innovation, announces the AH171xQ series, a breakthrough range of Hall Effect latches optimized for automotive and industrial applications. These latches are perfect for various uses, including precise speed measurement in Brushless DC (BLDC) motors, angle and linear encoders, and position sensors.

The AH171xQ series offers a selection of options with three high-sensitivity settings (+/-7 Gauss, +/-18 Gauss, and +/-50 Gauss), ensuring accurate and dependable switching within a precise operational range. With a fast 30kHz sensing bandwidth, these latches support high-speed rotational sensing capabilities. They also provide robust safeguards against electrostatic discharge (ESD), featuring impressive ratings of 8kV Human Body Model (HBM) and 2kV Charged Device Model (CDM) protection.

Designed to meet AEC-Q100 Grade 0 standards, these latches incorporate a chopper-stabilized design and internally compensated regulator for reliable temperature performance. Engineered for versatility, they reliably operate across a wide supply voltage range of 2.4V to 5.5V and a temperature span of -40°C to +150°C. Manufactured in IATF 16949-certified facilities, they fully support Production Part Approval Process (PPAP) documentation.

The AH171xQ series latches are conveniently packaged in the compact SOT23 form factor, making them a space-efficient solution. With exceptional sensitivity, temperature stability, and strong protection features, Diodes Corporation's Hall Effect latches offer an outstanding choice for industries seeking top-tier electronic components to enhance their automotive and industrial applications.
