FUNCTION
Power Input
When a magnetic field enters the hall element and exceeds the operate point BOPS (or less than
BOPN), the output turns on (output is low). When the magnetic field is below the release point BRPS
(or above BRPN), the output turns off (output is high). It is designed with open drain configuration
and connecting a pull up resistor from VOUT to VDD is necessary. It cannot be floating.
Ground Connection.
