Free Delay Time Setting
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.
