Description

The DPO2036 provides 4 channels of over-voltage protection over the CC1/2 & SBU1/2 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 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.

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.

The DPO2036 is housed in the low-profile and space-saving UQFN2020-12 (Type B) package which is manufactured with environmental-friendly material.
