The AH3781-SA-7 from Diodes Incorporated is a high-voltage, high-sensitivity Hall-effect latch IC designed for applications such as brushless DC motor commutation, flow meters, and position sensors. It features a wide operating voltage range from 3.0V to 28V, making it suitable for various industrial and consumer applications.
This device utilizes a chopper-stabilized architecture for superior temperature stability and minimal switch point drift. The output pin includes an internal pullup resistor, and the device offers an output overcurrent limit for added robustness. It is designed for bipolar latch operation, switching on with a South pole and off with a North pole of sufficient strength.
The AH3781-SA-7 is supplied in an industry-standard SOT-23-3 surface-mount package. It operates reliably over a temperature range of -40°C to +125°C. The device is also RoHS 3 compliant, lead-free, and halogen-free.
Key features include high sensitivity with typical operate and release points of ±25G, an internal pullup resistor on the output, and Zener clamps on supply and output pins for protection. Its robust design and wide operating parameters make it a reliable choice for demanding sensing applications.
