DPO2036
4-CH OVER-VOLTAGE PROTECTION FOR CC/SBU PINS ON USB TYPE-C
Description
Pin Assignments
The DPO2036 provides 4 channels of over-voltage protection over
®
the CC1/2 & SBU1/2 pins which are connected to the USB Type-C
(Top View)
connector. The 4 channels are divided into two pairs, one pair of
channels protect the CC1 and CC2 pins from being shorted to the
VBUS, one pair of channels protect the SBU1 and SBU2 pins from
being shorted to the VBUS. Whenever the voltage threshold set for any
of the two pairs of channels is reached, the exception condition
becomes valid and the low-active flag FAULTB is subsequently
asserted.

Thermal Pad
This device is designed to draw its operating voltage primarily from
the system power, VVSYS, which is either the always-ON 3.3V/5V
existed within the system or the 1-cell battery inside the mobile
system. Under the circumstance when the battery inside a mobile
system is fully depleted, DPO2036 can obtain power from the external
peripheral system connected to the USB Type-C connector. The
DPO2036 supports the dead battery mode by having both of the
CC1C and CC2C pins tied to the pull-down resistor RD (resistor value
per the USB Type-C Specification) embedded in the device.
