Hi,
I would like to know if nPM1300 supports an input voltage of 4V for Vbus. According to the datasheet, the recommended operating condition for Vbus is from 4V to 5.5V. However, charging only starts when Vbus is above 4.4V, and the full charge current is only reached at 5V (during CC phase). Just wondering if this is the expected behavior and if there is any register settings that we can tweak in the IC to enable support for 4V Vbus (I only found the current limiter option for Vbus in the datasheet). Thanks!
