Battery Protection IC,  
Integrated Power MOSFET,  
1-Cell Lithium-Ion Battery  
Overview  
www.onsemi.com  
MARKING  
The LC05732ARA is a protection IC for 1−cell lithium−ion  
batteries with integrated power MOS FET. Also it integrates highly  
accurate detection circuits and detection delay circuits to prevent  
batteries from over−charging, over−discharging, over−current  
discharging and over−current charging.  
In addition, main system can execute the power−on reset of itself  
by turning off the charge FET and discharge FET of LC05732ARA for  
a certain time period, with a reset signal.

LC05732ARA  
DESCRIPTION OF OPERATION  
1. Normal mode  
over−discharging (Tuv), discharging will be shut off,  
internal power FETs as DCHG_SW is turned off.  
This is the over−discharging mode.  
After detecting over−discharging, CS pin will be  
pulled up to VCC by an internal resistor Rcsu and  
the bias of internal circuits will be shut off.  
(Shut−down mode)  
LC05732ARA controls charging and discharging by  
detecting cell voltage (VCC) and controls S2−S1  
current. In case that cell voltage is between  
over−discharge detection voltage (Vuv) and  
over−charge detection voltage (Vov), and S2−S1  
current is between charge over−current detection  
current (Ioch) and discharge over−current detection  
current (Ioc), internal power MOS FETs as  
CHG_SW, DCHG_SW are both turned ON.  
This is the normal mode, and it is possible to be  
charged and discharged.  
In shut−down mode, operating current is suppressed  
under 0.1 uA (max).  
The recovery from stand−by mode will be made by  
internal circuits biased after the connecting charger.  
By continuing to be charged, if cell voltage  
increases more than over−discharge detection  
voltage (Vuvr) over the delay time of  
2. Over−charging mode  
Internal power MOSFET CHG_SW turns off if cell  
voltage becomes greater than or equal to  
over−charge detection voltage (Vov) over the delay  
time of over−charging (Tov).  
over−discharging (Tuvr), internal power MOS FETs  
as DCHG_SW is turned on and normal mode will be  
resumed.  
This is the over−charging detection mode.  
The recovery from over−charging will be made after  
the following two conditions are satisfied.  
1. Charger is removed from IC.  
In over−discharge detection mode, charging  
over−current detection does not operate.  
By continuing to be charged, charging over−current  
detection starts to operate after cell voltage goes up  
more than over−discharge release voltage (Vuvr).  
4. Discharging over−current detection mode 1  
Internal power MOS FET as DCHG_SW will be  
turned off and discharging current will be shut off if  
CS pin voltage becomes greater than or equal to  
discharging over−current detection current (Ioc) over  
the delay time of discharging over−current (Toc1).  
This is the discharging over−current detection mode  
1.  
2. Cell voltage decreases under over−charge release  
voltage (Vovr) over the delay time of over−charging  
releasing (Tovr) due to discharging through a load.  
Consequently, internal power MOS FET as  
CHG_SW will be turned on and normal mode will  
be resumed.  
In over−charging mode, discharging over−current  
detection is made only when CS pin increases more  
than discharging over−current detection current  
2(Ioc2), because discharge current flows through  
parasitic diode of CHG_SW FET.  
In discharging over−current detection mode 1, CS  
pin will be pulled down to VSS with internal resistor  
Rcsd.  
If CS pin voltage increases more than discharging  
over−current detection current 2 (Ioc2) over the  
delay time of discharging over−current 2 (Toc2),  
discharging will be shut off, because internal power  
FETs as DCHG_SW is turned off. (short−circuit  
detection mode)  
The recovery from discharging over−current  
detection mode will be made after the following two  
conditions are satisfied.  
1. Load is removed from IC.  
2. CS pin voltage becomes less than or equal to  
discharging over−current release current (Iocr) over  
the delay time of discharging over−current release  
(Tocr1) due to CS pin pulled down through Rcsd.  
Consequently, internal power MOS FET as  
DCHG_SW will be turned on, and normal mode will  
be resumed.  
After detecting short−circuit, CS pin will be pulled  
down to VSS by internal resistor Rcsd.  
The recovery from short circuit detection in  
over−charging mode will be made after the  
following two conditions are satisfied.  
1. Load is removed from IC.  
2. CS pin voltage becomes less than or equal to  
discharging over−current detection current 2 (Ioc2)  
due to CS pin pulled down through Rcsd.  
Consequently, internal power MOS FET as  
DCHG_SW will be turned on, and over−charging  
detection mode will be resumed.  
5. Discharging over−current detection mode 2 (short  
circuit detection)  
Internal power MOS FET as DCHG_SW will be  
turned off and discharging current will be shut off if  
CS pin voltage becomes greater than or equal to  
discharging over−current detection current2 (Ioc2)  
over the delay time of discharging over−current 2  
(Toc2).  
3. Over−discharging mode without Auto Wake Up  
function  
If cell voltage drops lower than over−discharge  
detection voltage (Vuv) over the delay time of  
This is the short circuit detection mode.  
www.onsemi.com  
8
LC05732ARA  
In short circuit detection mode, CS pin will be  
pulled down to VSS by internal resistor Rcsd.  
The recovery from short circuit detection mode will  
be made after the following two conditions are  
satisfied.  
*Internal current flows out through CS and S2  
terminals.  
After charger is removed, it flows through parasitic  
diode of CHG_SW FET.  
Therefore, CS pin voltage will go up more than  
charging over−current release current (Iochr).  
So CS pin voltage is not an indispensable condition  
for recovery from charging over−current detection.  
7. 0 V Battery Protection Function  
This function protects the battery when a short circuit  
in the battery (0 V battery) is detected, at which point  
charging will be prohibited.  
When the voltage of a battery is below 1.4 V (max), the  
gate of the charging control FET is fixed to the  
PAC−Terminal voltage, at which point charging will be  
prohibited.  
If the voltage of the battery is greater than the 0 V  
battery prohibit voltage (Vinh), charging will be  
enabled.  
a. Load is removed from IC.  
b. CS pin voltage becomes less than or equal to  
discharging over−current release current (Iocr) over  
the delay time of discharging over−current release  
(Tocr1) due to CS pin pulled down through Rcsd.  
Consequently, internal power MOS FET as  
DCHG_SW will be turned on, and normal mode will  
be resumed.  
6. Charging over−current detection mode  
Internal power MOS FET as CHG_SW will be  
turned off and charging current will be shut off if CS  
pin voltage becomes less than or equal to charging  
over−current detection current (Ioch) over the delay  
time of charging over−current (Toch).  
This is the charging over−current detection mode.  
The recoveries from charging over−current detection  
mode will be made after the following two  
conditions are satisfied.  
8. Reset mode  
In case of normal mode, internal power MOS FET  
as CHG_SW and DCHG_SW will be turned off and  
charging and discharging current will be shut off if  
RSTB pin voltage becomes less than or equal to  
low−level input voltage (VIL) over the delay time of  
reset pulse width(Tw_res).  
This is the reset mode.  
The recovery from reset mode will be made itself  
after the reset release time (Tres).  
1. Charger is removed from IC and CS pin will  
increase by load connection.  
2. CS pin voltage becomes greater than or equal to  
charging over−current release current (Iochr) over  
the delay time of charging over−current release  
(Tocrh).  
Consequently, internal power MOS FET as  
CHG_SW will be turned on, and normal mode will  
be resumed.  
Consequently, internal power MOS FET as  
CHG_SW and DCHG_SW will be turned on, and  
normal mode will be resumed.
