Monitoring Voltages Other than V CC
The Typical Operating Circuit for the MAX834/MAX835

monitored, as shown in Figure 4. Calculate V TRIP as in

When monitoring voltages other than V CC , ensure that
the maximum value for V MON is not exceeded:

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
(UNITS ARE OHMS AND VOLTS)

relaxes to its open-circuit voltage when the load dis-
connects. 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.
