Dear all,
I'm trying to do the "Design Steps" with the EVM board, EVM software and a 10S1P li-Ion battery. At step 3, i set the voltage divider to 42000mV, VOLSEL is set and Number Of Cells is 10. There is no voltage on the bat pin of the chip and i expect about 750mV pulse. VEN pin is pulsing right, i can see the pulse on one side of R27 and then, on TP2, nothing! J2 48V is shorted and J5 two MultiCell are shorted too! I can measure the 16.5K resistor, but there is 0V on TP2 or BAT pin. When i do a voltage calibration, the EVM software pop-up a message that say the voltage is too low.
I tried a 1S config with 4.5V on BAT+ & BAT- and the calibration software measured 4000mV, so i assume this pin is allright?!?
I'm doing something wrong?
Best regards,
Pierrick.
