DIODES Incorporated Magnetic Sensors - Magnetic Sensors - Switches (Solid State) - AH3766Q-SA-7 AH3766Q-SA-7

The AH3766Q-SA-7 is a high-voltage, medium-sensitivity Hall-Effect latch IC designed for automotive applications, including brushless DC-motor commutation, speed measurement, and position sensing. It operates within a supply voltage range of 3.0V to 28V and features a chopper stabilized architecture for enhanced temperature stability and minimal switch point drift. The device includes a single open-drain output that is activated by a South pole magnetic field and deactivated by a North pole, with typical operate and release points of +110G and -110G, respectively. This sensor is AEC-Q100 qualified, ensuring reliability in automotive environments, and is capable of operating in temperatures ranging from -40¬8C to +150¬8C. It also incorporates protective features such as a reverse blocking diode, Zener clamps on the supply and output pins, and an overcurrent limit on the output. The AH3766Q-SA-7 is available in industry-standard SOT23 and SIP-3 packages, making it suitable for various applications requiring robust magnetic sensing solutions.
