Overcurrent Detection Value Setting
The overcurrent detection value V
TH
for this IC series is 0.2 V (Typ) and the bias current is 200
μ

The power MOS FET peak current value before the current limiter goes into operation is derived from the
following equation.

form a low-pass filter, determined by their time constants, that prevents malfunctions
from current spikes when the power MOS FET is turned on or off.
