Description
BAT
2
Battery Connection - This pin is wired to the positive terminal of a single cell lithium ion/polymer battery.
CCP
11
Charge Current Programming Pin - A resistor (R
CCP
) is connected between this pin and GND. The constant
charging current is determined by the following relationship: R
CCP
= 50.648 x I
CCL
with R
CCP
in k
and
I
CCP
in amps.
Charge Indicator - This pin is a logic low level when the battery is being charged, provided V
SYS
is
≥
4.4V. It is
capable of driving the series combination of an LED and resistor that is powered from the SYS pin.
CHG
14
CMP
1
Compensation – Connect a 0.1μF capacitor from CMP to SYS.
CTP
12
Charge Termination Programming Pin – A resistor (R
CTP
) is connected between this pin and GND. The
charge termination taper current is determined by the following relationship: R
CTP
=0.7354 x I
TERM
with R
CTP
in k
and
I
TERM
in amps.
USB Current Limit Programming Pin – A resistor (R
CUS
) is connected between this pin and GND. The high
level USB charge current is determined by the following relationship: I
USB
= 1050 / R
CUS
.
Main DC Present – A low level on this logic output indicates that the Main DC power source (typically the wall
adapter) is applied.
Done Indicator - This pin is a logic low level when the battery charge cycle is complete. It is capable of driving
the series combination of an LED and resistor that is powered from the SYS pin.
