WSH41FC-XPAN2 - Hall Effect Sensor IC SIP-4L (70 Gauss)

The WSH41FC chip combines a Hall sensor, complementary output drivers, and a frequency generator, making it ideal for applications such as speed measurement, revolution counting, positioning, and DC brushless motor control. It features a temperature-compensated voltage regulator, a differential amplifier, a hysteresis controller, and open-collector output drivers that can handle up to 400mA and 10mA current loads respectively. Additionally, an on-chip protection diode is included to protect against reverse power faults. The chip also includes a temperature-dependent bias that adjusts the supply voltage for the hall plates and the switching points for decreasing magnet induction at higher temperatures, resulting in appropriate open collector output switching.
