Description
active-HIGH signal to start high current charging; when not in use, leave this pin open
active-HIGH output; 5 V tolerant; external 100 k pull-down resistor
input supply voltage or battery source; 3.0 V to 4.5 V
Remark: Below 3.0 V, USB full-speed and low-speed transactions are not guaranteed to
work, though some devices may work with the ISP1704A at these voltages.
