Notes

24.

Filtering is shared with CHRGRAW (shorted at board level). 2.2 µF is typically included at the CHRGRAW pin.

25.

6.5 µF is the maximum allowable capacitance on VBUS including all tolerances of filtering capacitance on VBUS and CHRGRAW (which

are shorted at the board level).

Characteristics noted under conditions -40

°C ≤ T

A ≤ 85 °C, GND = 0 V unless otherwise noted. Typical values noted reflect

the approximate parameter means at TA = 25 °C under nominal conditions, unless otherwise noted.
