Hi TI team,
Recently, we are observing a drop in a group of voltages (By group i mean the 5 channel groups as per IC structure). On analysis, we found a drop across diode that connects VC5 to VC5X, VC10 to VC10X and VC15 to BAT pin. This drop ranges from 200mV to 800mV and depending on it, the cell voltages dip, We are also seeing a similar drop on capacitors connecting VC5X to VC5B and VC10X to VC10B.
Voltages between VC10X to Cap3 and so on seem stable at 3.29V which means the ADC power is regulated.
Capacitors between VC10X to Cap3, VC5X to Cap2, Cap to GND are 1uF.
Please let us know the reason for this and any other info that you may require.
