Monitoring V oltages Other than V
CC
The typical operating circuit for the MAX834/MAX835
monitors V
CC
. Voltages other than V
CC
can easily be
monitored, as shown in Figure 4. Calculate V
TRIP
as
in the section Programming the Trip Voltage. When
monitoring voltages other than V
CC
, ensure that the
maximum value for V
MON
is not exceeded:
V
MON(MAX)
= (V
CC
- 1)(R1 + R2) / R2

The circuit in Figure 5 is designed to prevent a lead-
acid battery or a secondary battery such as an NiCd,
from sustaining damage through deep discharge. As
the battery reaches critical undervoltage,
OUT
switches
low. Q1 and Q2 turn off, disconnecting the battery from
the load. The MAX835’s latched output prevents Q1 and
Q2 from turning on again as the battery voltage relaxes
to its open-circuit voltage when the load disconnects.
CLEAR can be connected to a pushbutton switch, an
RC network, or a logic gate to reset the latch when the
battery is recharged or replaced.
