In a significant expansion of its product line, Diodes Incorporated introduces the AH371xQ series, an advanced Hall-effect latch designed exclusively for automotive use. This innovative series features a Hall plate design, enhancing overall performance and versatility in automotive applications.
Enhanced Performance for Automotive Systems
The AH371xQ series proves invaluable across various applications, ranging from controlling brushless DC motors to operating valves and serving in linear and incremental rotary encoders for precise position-sensing tasks.
Operating within a broad range of 3V to 27V, with 40V load dump protection, the series is well-suited for diverse automotive systems. It significantly contributes to vehicle comfort and efficient engine management, impacting tasks such as window lifting, sunroof movement, tailgate mechanisms, seat motors, cooling fans, water/oil pumps, and speed measurement.
Technological Features and Flexibility
The Hall-effect latches in this series employ a chopper-stabilized design, effectively minimizing thermal variation effects and enhancing stray field immunity. The series ensures prompt and reliable operation with a swift typical power-on time of 13µs. Engineers benefit from the flexibility of choosing from six sensitivity ranges (25 to 140 gauss), allowing for customization in sensing distances and magnet types.
Robust Design for Reliability
Featuring open-drain outputs that accommodate varied external pull-up voltages, the AH371xQ series prioritizes robust protection. It includes an 8kV human body model ESD rating, a reverse blocking diode, overcurrent protection, and an overvoltage clamp.
Adherence to High Automotive Standards
The AH371xQ series meets and exceeds high automotive standards, being AEC-Q100 Grade 0 qualified and manufactured in IATF 16949 certified facilities. The series supports Production Part Approval Process (PPAP) documentation and is available in various packages, including SOT23, SC59, and SIP-3, with the AH3712Q also offered in U-DFN2020-6.
