I would like to use the BAT sense input to boost the OUT voltage by approximately 50mV to account for cable losses in a charging application. I am using a 10K/1M voltage divider between OUT and BAT. The values are intentionally high to minimize battery drain at charge complete. This seems to work well when I am charging a battery and I end up with the desired charge complete voltage of 4.2V. However the LED behavior is not as expected when there is no battery present. The PG# LED is off and the STAT1 and STAT2 LEDs alternate on/off at about a 0.5 to 1Hz rate. The datasheet states that PG# turns on when a valid VCC is detected. My VCC is stable at 5V. If I start with a 6V supply I do not see the weird LED behavior but if I slowly increase VCC from 5V to 6V, the problem persists. Do you have an explanation for the strange LED behavior?
