BD4140HFV_09 Datasheet, PDF (1/9 Pages) Rohm – PGOOD IC for PC

Hi-performance Regulator IC Series for PCs
PGOOD IC
for PC
BD4140HFV
No.09030EBT18
●Description
BD4140HFV is 1ch reset IC for watching the voltage. The detected voltage is 0.5V, and it is available to several kinds of
voltage with additional external resistance. For the independent supply voltage (VCC), the “L” level of voltage is guaranteed
in case the watching input voltage is also low.
●Features
1) Open drain output type
2) Built in Under Voltage LockOut (UVLO) circuit
3) HVSOF5 package : 1.6×1.6×0.6(mm)
●Applications
Laptop PC, Desktop PC, LCD-TV, Printer, STV, Digital appliances
●Absolute maximum ratings (Ta=25℃)
