PIN CONFIGURATION
PIN DESCRIPTION
Pin Number
Symbol
Description
1
V
M
NC
Negative Battery Pack Terminal - connection for external negative terminal of the battery pack.
2
No Connection, do not connect this pin.
3
V
DD
Dual Cell Positive Terminal - connection for positive terminal of dual series connected LiI+ cells.
4
C
D
Delay Capacitor Connection - an external capactior connected across C
and Vss allows additional
charge time (DL2, see Detailed Description ) after a charge error has occured. Suggested capacitor
values are shown in DL2 Period vs. Capacitance Curves.
5
V
C
Dual Cell Center Tap Connection - monitors individual battery voltages for overcharge and
overdischarge errors.
6
Is
Current Sense Comparator Input - monitors load current for short circuit conditions . If V
ILIMIT
is
exceeded, then DCO opens the low-side switch, disconnecting the cells.
7
V
SS
Dual Cell Negative Terminal - connection for negative terminal of dual series connected LiI+ cells.
8
DCO
Low-side Switch Gate Driver Output - drives the gate of two external source connected n-channel
MOSFETs. DCO swings from V
OL
to V
DD
.
