DH43F is a Hall effect sensor switch circuit designed and produced based on bipolar semiconductor technology. The device integrates a Hall effect chip, a voltage regulator, a reverse voltage protector, a signal amplification processing circuit, a Schmitt trigger and an open collector output driver transistor. The internal compensation characteristics of DH43F make its sensitivity slightly increase with temperature, which is particularly suitable for matching with commonly used low-cost magnetic steel. The enhanced output drive circuit can drive a larger current and reduce the internal power consumption of the device. DH43F can withstand 60V high voltage shock. The above characteristics greatly improve the reliability of the device, which is very suitable for use as a solid-state electronic switch in products such as automobiles, industrial appliances and household appliances.
