VDD level is in between “Vdet1” and 
“Vdet1-Vhys1” in the T63H0001A version. 
The output of Dout pin, the output of 
over-discharge detector/VD2, switches to 
“Low” after internally fixed delay time passed, 
when discharging voltage crosses the detector 
threshold from a high value to a value lower than 
Vdet2. An excess load current can be sensed and 
cut off after internally fixed delay time passed 
through the built in excess current detector, VD3, 
with Dout being enabled to low level. Once after 
detecting excess current, the VD3 is released

and Dout level switches to “H” by detaching a 
battery pack from a load system. 
Further, short circuit protector makes Dout level 
to “L” immediately with external short circuit 
current and removing external short circuit leads 
Dout level to “H”. After detecting 
over-discharge, supply current will be kept 
extremely “L’ by halting some internal circuits 
operation. The output delay of over-charge 
detectors can be set by connecting external 
capacitors. Output type of Cout and Dout are 
CMOS. SOT-23-6 is available.
