ISO1540: VCC1, VCC2 Functional mode correlation

Ash Jaber

Part Number: ISO1540
Other Parts Discussed in Thread: ASH

Functional Modes on page 20 of the datasheet, which dictate the power states, versus input and output conditions. The stated VCC1 and VCC2 levels (2.1V or 2.8V) appear inconsistent with the Operating Conditions listed on page 6, we do not find a correlation between the listed 2.8V on page 20, against the values in the Operating Conditions on page 6.

Could you clarify this?

    Hi Ash,

    Thank you for notifying us about the voltages (2.1V & 2.8V) mentioned in Table 2 of the datasheet not being explained or referred elsewhere. These are the UVLO voltages where 2.1V is VCC(UVLO-) and 2.8V is VCC(UVLO+) which I understand are not mentioned elsewhere in the datasheet. I will work with the team to see if these two parameters can be added to recommended operating conditions or explained as a note along side Table 2.

    Thanks again for your inputs.
