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.
