Pin Description
Pin No.
Name
I/O
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
CC. The battery voltage is
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
CC disables the low-voltage detection.
3LV
Output
Output of the low-voltage detection. This pin is a NPN open-collector output that
goes to low impedance state when LV
ENB is pulled LOW and the battery voltage is
below the threshold set by LV
SEL. LV stays in HIGH impedance state at any battery
voltage when LV
ENB is pulled HIGH to VCC. LV can be used for turning on a low
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
CS, connected
between the battery’s negative terminal and GND. The maximum charge current is
regulated to a value of 100mV/R
CS.
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.
