IS31PW8200
LI+ DUAL BATTERY CONTROLLER
GENERAL DESCRIPTION
The IS31PW8200 is a highly integrated IC to serve as
the control logic for a system with multiple power
sources. It integrates a mini-charger’s path power
MOS with a switchable bulk and saves the external
diode in mini-charger path. Also, it directly drives the
internal P-channel MOSFETs to select the power path
for the system and manages dual battery sources for
charge and discharge. The power path selection is
made based on the present voltage of the power
sources and the state of charge of the batteries.
Additionally, IS31PW8200 integrates an I2C block to
communicate with the Base Band. At start up, the
baseband reads out the status of the dual battery
sources. During operation, if the status changes,
IS31PW8200 provides an interrupt to notify the
baseband to update the information of the dual
battery sources.
IS31PW8200 is available in QFN-20(3mm × 3mm)
package. It operates from 2.4V to 5.5V over the
temperature range of -40°C to +85°C.

SWITCH CONDITION IN CHARGE MODE (WITH ADAPTER PLUGGED IN):
Charge rules:
When the adapter is plugged in, the PMIC charges the supply battery and the internal charger provides a small
current for the unused battery. Internal charger provides a 20mA current for the unused battery which below VTH2
until the voltage of the battery reaches VTH2 then provides a 150mA current.
The voltage of battery changes during charging. The charging rules should follow the switch condition below. The
internal charger will disconnect automatically if batteries are both full.
State 1: If VA-BAT ≤ VTH2 and VB-BAT ≥ VTH1, B-BAT
provides power. The PMIC charges up B-BAT and
IS31PW8200 provides small current (20mA) for A-BAT
by internal charger at the same time. The battery
source will not switch until VA-BAT reaches to VTH1+VHY.
State 2: If VA-BAT charges up to VTH1+VHY and VB-BAT ≥
VTH1, switch to A-BAT providing power. The PMIC
charges up A-BAT and IS31PW8200 provides small
current (150mA) for B-BAT by internal charger at the
same time until batteries are both full.
State 3: If VA-BAT ≤ VTH2 and VTH2 ≤ VB-BAT ≤ VTH1, B-BAT
provides power. The PMIC charges up for B-BAT and
IS31PW8200 provides small current (20mA) for A-BAT
by internal charger at the same time. The battery
source will not switch until VA-BAT reaches VTH2+0.1V.
http://www.DataSheet4U.net/
State 4: If VA-BAT charges up to VTH2+0.1V and VTH2 ≤
VB-BAT ≤ VTH1, switch to A-BAT providing power. The
PMIC charges up for A-BAT and IS31PW8200
provides small current (150mA) for B-BAT by internal
charger at the same time until batteries are both full.
State 5: If VA-BAT ≤ VTH2 and VB-BAT ≤ VTH2, dual batteries
disconnect with VBAT. At this moment, the PMIC
doesn’t charge up any batteries and IS31PW8200
provides small current (20mA) for dual batteries by
internal charger until one of batteries is charged up to
VTH2+0.1V and offer power by this battery.
State 6: If VA-BAT charges up to VTH2+0.1V first and
VB-BAT ≤ VTH2, A-BAT provides power. The PMIC
charges up A-BAT and IS31PW8200 provides small
current (20mA) for B-BAT by internal charger at the
same time until batteries are both full. It operates
opposition situation if VB-BAT charges up to VTH2+0.1V
first.
Note: Stop charging when the B-BAT is full. If VB-BAT falls below 4.0V for a period of more than 2s, B-BAT resumes
charging again.
