Symbol names ending with underscore N, for example, NAME_N, represent active LOW signals.
All ground pins should normally be connected to a common ground plane.
I = input only; O = output only; I/O = digital input/output; OD = open-drain output; AI/O = analog input/output; AI = analog input; P =
power; (AI/O)(I) = analog input/output digital input; AI/I = analog input digital input; G = ground supply; T = factory test pin

Description
charge pump capacitor input; connect a 220 nF capacitor between this pin and
pin 125
charge pump capacitor input; connect a 220 nF capacitor between this pin and
pin 124
charge pump input; connect to 3.3 V
port 2 analog (5 V input) and digital overcurrent input (active LOW); if not used,
connect to V
input, 5 V tolerant

Input: Port 1 OC1_N detection when port 1 is configured for host functionality
and an external power switch is used (active LOW); if not used, connect to
V
open-drain output of the power-switch flag pin
Output: V
for the OTG functionality; typically 50 mA current capability; the overcurrent
protection in this case is ensured by the internal charge pump current
limitation; only for port 1
