Image of Diodes AH371x High-Voltage Hall-Effect Latch Switch Family Diodes' AH371x is a family of high-voltage, high-performance Hall effect latches for brushless DC motor commutation, speed measurement, and incremental rotary and linear encoders/position sensors. These devices consist of six variants of magnetic operate and release points (BOP and BRP) ranging from a typical ±25 to ±140 Gauss.

This product family, with open drain output, is resistant to physical stress, and provides a solution for a wide range of industrial applications (AH371xA integrates pull-up resistors). To enhance system reliability, the entire family is specified over the whole operating range of 3 V to 27 V and -40°C to +125°C.

The AH371x family incorporates reverse blocking diodes, V_DD and output Zener clamps, output current limiting, and high ESD ratings (8 kV HBM/1 kV CDM). All the variants are available in industry-standard packages of SC59, SOT23 (Type S), and SIP-3 (bulk pack).
