AH431 Datasheet | Alfa Electronics

2-Wire Current unipolar switch 1. Product Introduction AH431 is a Hall effect sensor switch chip designed and produced based on bipolar semiconductor technology. The device is internally integrated with a Hall effect circuit, voltage regulator, signal amplification and processing circuit, Schmidt trigger, and a switch controlled current source circuit. The internal pensation characteristics of AH431 slightly increase its sensitivity with increasing temperature, making it particularly suitable for matching with monly used low-cost magnetic steels. Enhanced output drive circuits can drive larger currents and reduce internal power consumption of devices. AH431 can withstand 60V high-voltage impact. The above characteristics greatly improve the reliability of the device and are very suitable for use as solid-state electronic switches in products such as automobiles, industrial appliances, and home appliances. Provide TO92S inline packaging, SMT SOT23-3L packaging, and all packaging meets Ro HS standards. 2.
