FOperation notes

(1) FGS

When a high-level voltage is input to FGS, the FG output

is output even when power save is on (PS = low level).

Also, the Hall bias terminal stays in the operating state.

(2) Switching regulator

The BA6855AFM has a switching regulator pin.

The IC has an oscillator circuit, and the output is

compared to the low-level voltage detector output and

output on VREG.
