The battery cell temperature is
represented as a voltage input
to the SS6781B at this pin.
The acceptable voltage range
of VTS pin is 0.29VCC to
0.72VCC.
The
battery
temperature is regarded as too
high if the voltage of VTS pin is
lower than 0.29VCC, and is
otherwise regarded as too low
if the voltage of VT
higher than 0.72VCC.
PIN 5: VCC- Power supply input at 5V±10%.
For adjusting the slope of ∆T/∆t.
Acceptable voltage range for

to 3.8V. If voltage higher than
VCC-0.3V, the function
