DEVICE INFORMATION
TERMINAL FUNCTIONS
TERMINAL
I/O DESCRIPTION
NAME NO.
AC 4 I Charge input voltage from AC adapter
ACPG
(1)
18 O AC power-good status output (open-drain)
BAT 5, 6 I/O Battery input and output.
CE 9 I Chip enable input (active high)
DPPM 13 I Dynamic power-path management set point (account for scale factor)
ISET1 10 I/O Charge current set point for AC input and precharge and termination set point for both AC and USB
ISET2 7 I Charge current set point for USB port. (High = 500 mA, Low = 100 mA)
LDO 1 O 3.3-V LDO regulator
OUT 15, 16, 17 O Output terminal to the system
PG
(1)
18 O AC or USB power-good status output (open-drain)
PSEL 8 I Power source selection input (Low for USB, High for AC)
STAT1 2 O Charge status output 1 (open-drain)
STAT2 3 O Charge status output 2 (open-drain)
Timer program input programmed by resistor. Disable fast-charge safety timer and termination by tying
TMR 14 I/O
TMR to LDO.
TS 12 I/O Temperature sense input
USB 20 I USB charge input voltage
USBPG
(2)
19 O USB power-good status output (open-drain)
VBSEL
(2)
19 I Battery charge voltage selection
Ground input (the thermal pad on the underside of the package) There is an internal electrical connection
between the exposed thermal pad and VSS pin of the device. The exposed thermal pad must be
VSS 11 –
connected to the same potential as the VSS pin on the printed-circuit board. Do not use the thermal pad as
the primary ground input for the device. VSS pin must be connected to ground at all times.
(1) Pin 18 is PG for bq24038 and ACPG for bq24030/31/32A/35.
(2) Pin 19 is VBSEL for bq24038 and USBPG for bq24030/31/32A/35.
