Part Number: BQ24032A
Dear TI:
We have received our boards back from our assembly house and some boards function quiet differently.
Here is the schematic.
Some boards have the following measurements:
Vdppm = 3.512V
Vtmr = 2.47V
Viset1 = 2.46V
Vout = 4.33V
Some other boards are different (Charging looks like not working):
Vdppm = 4.13V
Vtmr = 0.79V
Viset1 = 0V
Vout = 4.4V
The load is about 100mA. And same AC adapter and battery were used for both cases.
Why the voltages are different on different boards? What could be the issue? Can the LDO be the power to the pull up resistors for CE/ISET2/PSEL?
Thanks,
Richard
