DESCRIPTION
NO
.
BAT
11
I
Battery voltage sense input. This input is tied directly to the positive side of the battery pack.
CC
13
O
Charge control output. CC is an open-drain pulldown output that is used to drive an external pass tran-
sistor for charge current and voltage control
ICOMP
4
I
Current loop compensation. This is the compensation for the fast charge current regulation loop.
OPTD
1
O
Optocoupler driver output. This open-collector output is used to provide feedback to the primary side
by driving an external optocoupler.
SCOMP
3
I
Supply loop compensation. This is the compensation for the VCC supply regulation loop.
Current sense input. Battery current is sensed via the voltage developed on this pin by an external
sense resistor.
SNS
12
I
STAT1
6
O
Charge status output 1 (open drain)
STAT2
7
O
Charge status output 2 (open drain)
TADJ
8
I
Termination adjust. This input is used to set the minimum current termination level during voltage regu-
lation phase.
TS
10
I
Temperature sense Input. Input for an external battery temperature monitoring.
VCC
2
I
VCC supply input.
Voltage loop compensation. This is the compensation for the battery regulation loop
VCOMP
5
I
VREF
9
O
Voltage reference output. This buffered output provides the internal bandgap voltage.
VSS
14
–
Ground input.
