Free Delay Time Setting
CMOS Voltage Detector IC
BD4142HFV
âGeneral Description
BD4142HFV is 1ch voltage detector IC for monitoring an
input voltage line. The default detected voltage is 0.5V
and is adjustable via external resistors. When monitoring
an input voltage supply, the IC outputs a HIGH signal via
a PGOOD pin when the supply rises above the threshold
and is LOW when below.
