Notes
11.
Preferred device TDK VLS252012 series at 2.5x2.0 mm footprint and 1.2 mm max height
12.
Preferably 0603 style 6.3 V rated X5R/X7R type at 35% total make tolerance, temperature spread and DC bias derating such as TDK
C1608X5R0J106M
13.
Preferably 0805 style 6.3 V rated X5R/X7R type at 35% total make tolerance, temperature spread and DC bias derating such as TDK
C2012X5R0J226M

Preferably 0603 style 6.3 V rated X5R/X7R type at 35% total make tolerance, temperature spread and DC bias derating such as TDK
C1608X5R0J475
15.
Output voltage when configured to supply VBUS in OTG mode can be as high as 5.75 V
16.
Vin is the low side of the inductor that is connected to BP.
Table 4. Static Electrical Characteristics
Characteristics noted under conditions -30
°C ≤ TA ≤ 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. Current in RTC Mode is from
LICELL = 2.5 V, in all other modes from BP = 3.6 V. External loads are not included.
