Hi,
The voltage at VBAT is 4.2V
RSET is 1.22 k ohm
LDO is 3.3V +/- 0.1V
DPPM is 3.76V
ACPG and USBPG LEDs turn on when connected to respective sources
TS grounded through 10k resistor and voltage is 1V on the 12th PIN
The problem is that battery isn't charging, even though STAT1 LED is always aglow. It just isn't drawing any current. I've also connected battery directly to power supply and it draws current (around 600-800 mA at 6V).
The other issue is that when I connect Load to the output, 2-5 ohm load, it drastically drops the input voltage, say from 5V to 3V, which messes up the entire system. We have a 3.3 V regulator at the output, after which Load is connected.
Any help would be highly appreciated.
