CMOS Voltage Detector IC

BD4142HFV

●General Description

●Key Specifications

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.

 Input voltage range:

 Detected voltage:

 PGOOD output ON resistance:

 Bias current:

3.0V to 5.5V

500mV(Typ)

100Ω(Typ)

7.5μA (Typ)

 Operating temperature range (Ta): -10℃ to +100℃

●Package
