PLANO, Texas--(BUSINESS WIRE)--Dec. 19, 2023-- Diodes Incorporated (Diodes) (Nasdaq: DIOD) adds the AH371xQ series of high-voltage Hall-effect latches to its product portfolio. These automotive-compliant devices feature a proprietary Hall plate design that boosts performance. They are used for brushless DC (BLDC) motor control, valve operation, linear and incremental rotary encoders, and position-sensing functions. Based on this, the AH371xQ series can support numerous in-vehicle comfort and engine management applications—including window power-lift and sunroof movement, tailgate opening/closing mechanisms, seat adjustment motors, cooling fans, water/oil pumps, and speed measurement.

These Hall-effect latches have an operating voltage range from 3V to 27V, with 40V load dump protection. This gives them the versatility to integrate into a wide variety of automotive systems. The devices have a chopper-stabilized design that mitigates the effects of thermal variation and provides enhanced stray field immunity. Their power-on time is typically 13µs.

Covering 25 gauss to 140 gauss, there is a selection of six sensitivity options, with tight operating windows and low temperature coefficients for switch points. These options give engineers scope for different magnetic operating (B_OP) and magnetic release (B_RP). Consequently, they can find the best fit in relation to the sensing distance and the magnets used. Open-drain outputs lead to greater external pull-up flexibility when it comes to voltages that are higher or lower than the supply voltage.

The latches in the AH371xQ series have an 8kV human body model (HBM) electrostatic discharge (ESD) rating. Protection features integrated into each of these devices include reverse blocking diode, overcurrent protection, and overvoltage clamp.

These new automotive-compliant Hall-effect latches from Diodes are AEC-Q100 Grade 0 qualified, manufactured in IATF 16949 certified facilities, and support PPAP documentation. The AH371xQ family is available in SOT23 (Type S), SC59, and SIP-3 (Bulk Pack) packages, while the AH3712Q is also supplied in U-DFN2020-6 (SWP) packages. The AH371xQ series is available at $0.32 in 1,000 piece quantities. These, and the full portfolio of Hall-effect sensors, are included in the Hall-effect sensor part selector.
