TPS3620-33-EP: Absolute Maximum Rating of VBAT and reverse voltage protection

TPS3620-33-EP: Battery Supply Current

Hi,

Please verify the Battery supply current.

The first page of the datasheet shown battery supply current is 100nA (max) however when I looking at the supply current vs supply voltage (Vbat = 2.6V) @ 85C shown around 16-17 uA. (page-8, figure 3)

I am looking for ultra low current when using Vbat. 

Thanks,

    Hi Mo, Fig. 3 shows the VDD current, not the VBAT current. If you look at the Electrical Specifications table on p. 4, VDD current has a maximum specification of 40 uA across all conditions and VBAT current shows a maximum specification of 100 nA when VOUT=VDD and 500 nA when VOUT=VBAT.

    Thanks,
