Description
Negative Battery Pack Terminal - connection for external negative terminal of the battery pack.
No Connection, do not connect this pin.
Dual Cell Positive Terminal - connection for positive terminal of dual series connected LiI+ cells.
Delay Capacitor Connection - an external capacitor connected across C D and Vss allows additional charge time
(DL2, see Detailed Description ) after a charge error has occurred. Suggested capacitor values are shown in
DL2 Period vs. Capacitance Curves.
Dual Cell Center Tap Connection - monitors individual battery voltages for overcharge and overdischarge errors.
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 cell
Dual Cell Negative Terminal - connection for negative terminal of dual series connected LiI+ cells.
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 .
