Compensation input for constant current regulation loop
CC
11
Negative terminal of battery
BATT-
12
System ground. The resistor placed between BATT- and GND monitors the current into the battery.
GND
13
Current sink for driving the external PNP current source
DRV
14
Shunt regulator. The voltage on V+ is regulated to +5V with respect to BATT-, and the shunt current
powers the MAX712/MAX713.
V+
15
Trip point for the under-temperature comparator. If the MAX712/MAX713 power on with the voltage-on
TEMP less than TLO, fast charge is inhibited and will not start until TEMP rises above TLO.
TLO
6
Sense input for temperature-dependent voltage from thermistors.
TEMP
7
Open-drain, fast-charge status output. While the MAX712/MAX713 fast charge the battery,
FASTCHG
sinks current. When charge ends and trickle charge begins,
FASTCHG
stops sinking current.
FASTCHG
8
PGM2 and PGM3 set the maximum time allowed for fast charging. Timeouts from 33 minutes to 264
minutes can be set by connecting to any of V+, REF, or BATT-, or by leaving the pin open (Table 3).
PGM3 also sets the fast-charge to trickle-charge current ratio (Table 5).
PGM2,
PGM3
9, 10
Trip point for the over-temperature comparator. If the voltage-on TEMP rises above THI, fast charge ends.
THI
5
PGM0 and PGM1 set the number of series cells to be charged. The number of cells can be set from
1 to 16 by connecting PGM0 and PGM1 to any of V+, REF, or BATT-, or by leaving the pin open (Table
2). For cell counts greater than 11, see the Linear-Mode, High Series Cell Countsection. Charging more
or fewer cells than the number programmed may inhibit
V fast-charge termination.
PGM0,
PGM1
3, 4
PIN
Positive terminal of battery
BATT+
2
Sets the maximum cell voltage. The battery terminal voltage (BATT+ - BATT-) will not exceed VLIMIT x
(number of cells). Do not allow VLIMIT to exceed 2.5V. Tie VLIMIT to VREF for normal operation.
