MAX712/MAX713
NiCd/NiMH Battery
Fast-Charge Controllers
Linear-Mode, High Series Cell Count
The absolute maximum voltage rating for the BATT+ pin
is higher when the MAX712/MAX713 are powered on. If
more than 11 cells are used in the battery, the BATT+
input voltage must be limited by external circuitry when
DC IN is not applied (Figure 15).
Efficiency During Discharge
The current-sense resistor, R SENSE , causes a small
efficiency loss during battery use. The efficiency loss is
significant only if R SENSE is much greater than the

battery stack’s internal resistance. The circuit in Figure
16 can be used to shunt the sense resistor whenever
power is removed from the charger.
Status Outputs
Figure 17 shows a circuit that can be used to indicate
charger status with logic levels. Figure 18 shows a
circuit that can be used to drive LEDs for power and
charger status.
