CMOS Voltage Detector IC
BD4142HFV
●General 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.
●Features
 Open Drain Output
 Built in Under Voltage LockOut (UVLO) Circuit
 Delay Time Controlled by External Capacitor
 Very small and low height package
 PGOOD HIGH Output
●Applications
Laptop PC, Desktop PC, LCD-TV, Printer, STB, Digital
Appliances, and more.
●Key Specifications
 Input voltage range:
3.0V to 5.5V
 Detected voltage:
500mV(Typ)
 PGOOD output ON resistance:
100Ω(Typ)
 Bias current:
7.5μA (Typ)
 Operating temperature range (Ta): -10℃ to +100℃
