DPO2039DABQ-13
4-CH OVER-VOLTAGE PROTECTION FOR CC/DIFF PINS ON USB TYPE-C
Description
Pin Assignments
The DPO2039DABQ-13 provides
4
channels of over-voltage
protection over the CC1/2 & DIFF1/2 pins which are connected to the
USB Type-C 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 DIFF1 and
DIFF2 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.

This device is designed to draw its operating voltage primarily from
the system power, VSYS, which is either the always-ON 3.3/5V 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, DPO2039DABQ-13 can obtain power from the external
peripheral system connected to the USB Type-C connector. The
DPO2039DABQ-13 is housed in the low-profile and space-saving U-
QFN3030-16 (Type B) package which is manufactured with
environmental-friendly material.
