AH4059 Hall Sensor is a kind of bipolar Hall switch with two complementary outputs. It is particularly suitable for double coil DC motor, double coil DC fan, speed measurement and rotation control. The sensor chip intergrated bandgap reference voltage source, Hall voltage generator, signal amplifier, hysteresis controller, reverse voltage protection diode, and circuit units such as an open-collector output driver with two complementary outputs with a sink current of 300mA. High-performance bandgap reference voltage source ensures consistent sensitivity of the sensor over a wide temperature range. Reverse voltage protection diodes avoid reverse power failures.
