, unless otherwise noted. Refer to Typical Operating Circuit All measurements are with respect to
BATT-, not GND.)
Note 1:
The MAX712/MAX713 are powered from the V+ pin. Since V+ shunt regulates to +5V, R1 must be small enough to allow at
least 5mA of current into the V+ pin.
Note 2:
Offset voltage of THI and TLO comparators referred to TEMP.
Note 3:
t
A
is the A/D sampling interval (Table 3).
Note 4:
This specification can be violated when attempting to charge more or fewer cells than the number programmed. To ensure
proper voltage-slope fast-charge termination, the (maximum battery voltage) ÷ (number of cells programmed) must fall
within the A/D input range.
