Description

1LV

SEL

Input

Low-voltage detection threshold Select. The threshold is 2.15V/cell when this pin is

pulled low to GND and 2.70V/cell when it is pulled up to V

sensed between CEL and CS pins.

2LV

ENB

Input

Low-voltage detection Enable. The low-voltage detection is enabled when this pin is

pulled Low to GND. Pulling this pin HIGH to V

3LV

Output

Output of the low-voltage detection. This pin is a NPN open-collector output that

goes to low impedance state when LV

below the threshold set by LV

voltage when LV

current source to recondition a deeply depleted battery.

4

GND

Ground

IC common.

5

CS

Input

Input for battery charge current and battery negative-terminal voltage sensing.

Battery charging current is sensed through an external resistor, R

between the battery’s negative terminal and GND. The maximum charge current is

regulated to a value of 100mV/R

6

CEL

Input

Battery positive-terminal voltage sensing.

7

EXT

Output

Output of the controller for driving a PNP transistor or P-MOSFET. The controller

modulates the current sinking into this pin to control the regulation of either the

charge current or the battery voltage.

8V

CC

Power Supply

IC power supply
