Thisoutputmaythereforebe usedtosupplycircuits
continuously, such as volatile RAMs, allowing the
use of a back-upbattery.
TheV
02
output can supply othernon essential5 V
circuits which may be powered down when the
system is inactive, or that must be powered down
to prevent uncorrect operationfor supply voltages
below the minimum value.
Theresetoutputcanbeusedas a”POWERDOWN
INTERRUPT”, permitting RAM access only in cor-
rectpowerconditions,orasa ”BACK-UPENABLE”
to transfer data into in a NV SHADOW MEMORY

when the supply is interrupted.
Thedisable functioncan be usedfor remoteon/off
controlof circuits connectedto theV
02
output.
APPLICATION SUGGESTIONS
Figure 2 illustrate how the L4902A’sdisable input
may be used in a CMOS
μ
Computer application.
TheV

regulator(lowconsumption)supplyperma-
nently a CMOS time of day clock and a CMOS
μ
computer chip with volatile memory. V
02
output,
