Description
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.
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.
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 V
CC
. LV can be used for turning on a low
current source to recondition a deeply depleted battery.
IC common.
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
.
Battery positive-terminal voltage sensing.
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.
