Application Circuits 
Application Hints 
R1 and C1 will stabilize a supply voltage to 
the T63H0002. A recommended R1 value is less 
than 1kOhm. A larger value of R1 leads higher 
detection voltage, makes some errors, because 
of shoot through current flowed in the 
T63H0002. 
R2 and C2 will stabilize a V- pin voltage. 
The resetting from over-discharge with 
connecting a charger possibly be disabled by 
larger value of R2.  
Recommended value is less than 1kOhm. 
After over-charge detection even connecting 
battery pack to a system probably could not 
allow a system to draw load current by a larger 
R2xC2 time constant in the T63H0002.  
Recommended C2 value is less than 1uF. 
R1 and R2 may cause power consumption 
over rating of power dissipation of the 
T63H0002 and a total of “R1+R2” should be 
more than 1kOhm. 
The time constants R1xC1 or R2xC2 must 
have a relation as below: 
R1xC1<=R2xC2 
Because in case that R1xC1, time constant for 
VDD pin, would be larger than R2xC2, time 
constant for V- pin then the T63H0002 might be 
into a standby mode after detecting excess 
current or short circuit current.
