SLVS658B – MARCH 2006 – REVISED FEBRUARY 2007
NAME PIN I/O DESCRIPTION EXTERNAL REQUIRED COMPONENTS
(SEE APPLICATION DIAGRAM)
AC 7 I Adapter charge input voltage, connect to 1- µ F (minimum) capacitor to AGND1 pin to minimize
AC_DC adapter positive output terminal overvoltage transients during AC power hot-plug events.
(dc voltage)
ADC_REF 22 I/O ADC internal reference filter or ADC 4.7 µ F (minimum) to 10 µ F (maximum) capacitor connected to
external reference input AGND2 pin
AGND0 16 – Analog ground connection Connect to analog ground plane
AGND1 48 – Analog ground pin Connect to analog ground plane
AGND2 25 – Analog ground pin Connect to analog ground plane
ANLG1 24 I Analog input to ADC, programmable Can be used to monitor additional system or pack parameters
current source output
ANLG2 23 I Analog input to ADC, programmable Can be used to monitor additional system or pack parameters
current source output
BAT 17, I/O Battery power Connect to battery positive terminal. Connect 10- µ F capacitor
18 (minimum) from BAT pin to AGND1 pin.
BLUE 1 O Programmable blue driver, open drain Connect to BLUE input of RGB LED
output, current sink output when active.
DPPM 14 I Dynamic power path management External resistor from DPPM pin to AGND1 pin sets the DPPM
set-point regulation threshold. 1-nF (minimum) capacitor to from DPPM
to AGND1 sets BAT to OUT short circuit blanking delay when
battery is hot-plugged into system
FB3 41 I/O White LED duty cycle switch output, LED External resistor from FB3 pin to PGND3 pin sets LED peak
current setting current. Connect 100 pF (minimum) filter capacitor to PGND3
pin.
GPIO1 43 I/O General purpose programmable I/O Power-up default: SM1 enable control, SM1 ON @ GPIO1=HI.
GPIO2 53 I/O General purpose programmable I/O Power-up default: SM2 enable control, SM2 ON at GPIO2 = HI.
GPIO3 54 I/O General purpose programmable I/O. Example: ADC conversion start trigger.
GREEN 56 O Programmable LED driver, open drain Connect to GREEN input of RGB LED
output, current sink output when active.
