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.

Description
external power-up reset; active LOW; when reset is asserted, it is
expected that bus signals are idle, that is, not toggling
input, 3.3 V tolerant
Remark: During reset, ensure that all the input pins to the ISP1761
are not toggling and are in their inactive states.

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
This pin has multiple functions:
5 V tolerant
port 2 analog (5 V input) and digital overcurrent input; if not used,
connect to V

Input: Port 1 OC1_N detection when port 1 is configured for
host functionality and an external power switch is used; if not
used, connect to V

power-switch flag pin
Output: V

ensured by the internal charge pump current limitation; only for
port 1
