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.
