BNEG
: Connect the negative terminal of the battery to
this pin.
PACK+
: Connect to the positive terminal of the battery.
This pin is available to the user.
CBPS
: This power supply bypass pin is connected to
PACK+ through an internal 10K resistor.
0.1 F capacitor must be connected between this pin and
BNEG.
An external
PACK–

tive terminal available to the user).
switch connects this terminal to the BNEG terminal to
The internal FET
give the battery pack user appropriate access to the bat-
tery. In an over-charged state, only discharge current is
permitted. In an over-discharged state, only charge cur-
rent is permitted.
SUB
: (DP Package Only) Do not connect. These pins
must be electrically isolated from all other pins. These
pins may be soldered to isolated coppper pads for
heatsinking. However, most applications do not require
heatsinking.
TCLK
: Production Test Mode pin. This pin is used to
provide a high frequency clock to the IC during produc-
tion testing. In an application this pin may be left uncon-
nected, or tied to BNEG.
