We are looking at using the ISL9113 in a battery-powered application that can expect the battery to provide 1.9 to 3.0 volts before the batteries should be replaced. We need it to produce a regulated 5V output at around an 80 - 120 mA load.
The datasheet is a bit confusing because it lists the input voltage range as 0.8-4.7 V, but then it lists a minimum start-up voltage as 3.0 V. The next line in the table lists a UVLO of 0.7 V.
So which is it? What minimum voltage is needed at the VBat terminal to run the device?
Hi Ron, I see you submitted these questions through our website's technical support system and was assigned Ticket 346971. I will answer that ticket shortly through our technical support system.
