VDD

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

VOUT

field is below the release point BRPS (or above BRPN), the output turns off (output

is high). It is design with open drain configuration and connecting a pull up

resistor from VOUT to VDD is necessary. It cannot be floating.
