Standalone USB Type-C and USB Power
Delivery Controller
MAX77958
General Description
Benefits and Features
The MAX77958 is a robust solution for USB Type-C CC
detection and power delivery (PD) protocol implementa-
tion. It detects connected accessories or devices by us-
ing Type-C CC detection and USB PD messaging. The
IC protects against overvoltage and overcurrent, and de-
tects moisture and prevents corrosion on the USB Type-
C connector. The IC also has a D+/D- USB switch and
BC1.2 detection to support legacy USB standards. It con-

● USB Type-C Support and USB-PD Support
• USB Type-C Version 1.3 and PD3.0 Compliant
• Mode Configuration: Sink/Source/Dual Role Port
• Programmable Power Supply (PPS) Sink Support
• Fast Role Swap (FRS) Initial Sink Support
• Alternate Mode Support
USB PD negotiation is complete, the IC configures an al-
ternate mode setting for external multiplexers.
The IC is compliant with USB Type-C Specification Re-
lease 1.3 and PD 3.0. It can be customized easily without
affecting the compliance.

The IC has an I C master that can read and write to other
• Cable Orientation and Power Role Detection
devices in the system so that its firmware can configure re-
lated devices without the main processor's assistance. For
example, it can configure an external charger based on
BC1.2 detection, CC detection, and PD communication.
