• Output Delay Time Shortening Function............................. By forcing a certain voltage to SEL pin, overcharge,

discharge voltage and current is reduced approximately 1/80.

Overcharge delay time can be shorten into around 4ms for

testing.

overdischarge, the output of COUT becomes “Hi-Z”, the output of DOUT becomes “L”.
