TERMINAL FUNCTIONS
I/O
DESCRIPTION
I
Charge input voltage from AC adapter
O AC powergood status output (open-drain)
I/O
Battery input and output.
I/O
I
Chip enable input (active high)
I
Dynamic power path management set point (account for scale factor)
I/O Charge current set point for AC input and precharge and taper set point for both AC and USB
I
Charge current set point for USB port. (High = 500 mA, Low = 100 mA) For bq24032 see half charge
current mode using ISET2.
O 3.3 V LDO regulator
O Output terminal to the system
I
Power source selection input (low for USB, High for AC)
O Charge status output 1 (open-drain)
O Charge status output 2 (open-drain)
I/O Timer program input
I/O Temperature sense input
I
USB charge input voltage
O USB powergood status output (open-drain)
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
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.
