Microprocessor Voltage Monitor with
Dual Over/Undervoltage Detection
Like all junction-isolated CMOS circuits, the ICL7665 has
an inherent four-layer or SCR structure that can be
triggered into destructive latchup under certain con-
ditions. Avoid destructive latchup by following these
precautions:

greater than V+ or less than ground, limit the input
current to 500 A maximum. Usually, an input volt-
age divider resistance can be chosen to ensure
the input current remains below 500 A, even
when the input voltage is applied before the
ICL7665 V+ supply is connected.
capacitor near the ICL7665. Rate-of-rise SCRs
rarely occur unless: a) the battery has a low
impedance—as is the case with NiCd and lead
acid batteries; b) the battery is connected directly
to the ICL7665 or is switched on via a mechanical
switch with low resistance; or c) there is little or no
input filter capacitance near the ICL7665. In line-
powered systems, the rate-of-rise is usually limited
by other factors and will not cause a rate-of-rise
SCR action under normal circumstances.

age on OUT1 and OUT2 to +18V and the maxi-
mum voltage on HYST1 and HYST2 to 18V below V+.
