MAX77958 Standalone USB Type-C and USB Power Delivery Controller General Description Benefits and Features The MAX77958 is a robust solution for USB Type-C CC Supports Autonomous or MCU Based Configuration detection and power delivery (PD) protocol implementa- No Firmware Development Needed in Autonomous tion. It detects connected accessories or devices by us- Configuration ing Type-C CC detection and USB PD messaging. The Customizable Based on Application Requirements IC protects against overvoltage and overcurrent, and de- Customizable Firmware tects moisture and prevents corrosion on the USB Type- USB Compliant Default Embedded Firmware C connector. The IC also has a D+/D- USB switch and Supports Customizable Actions on Events BC1.2 detection to support legacy USB standards. It con- Firmware Updates for Future Specification tains V switches for USB PD and an enable pin for CONN Revisions an external V boost or buck converter. When the CONN USB Type-C Support and USB-PD Support USB PD negotiation is complete, the IC configures an al- USB Type-C Version 1.3 and PD3.0 Compliant ternate mode setting for external multiplexers. Mode Configuration: Sink/Source/Dual Role Port The IC is compliant with USB Type-C Specification Re- Programmable Power Supply (PPS) Sink Support lease 1.3 and PD 3.0. It can be customized easily without Fast Role Swap (FRS) Initial Sink Support affecting the compliance. Alternate Mode Support 2 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- Integrated V Switch with OCP CONN lated devices without the main processor s assistance. For Support Try.Snk State example, it can configure an external charger based on Audio and Debug Accessory Sink/Source Mode BC1.2 detection, CC detection, and PD communication. Supports BC1.2 Legacy/Proprietary Charger Detection The IC has an interrupt output pin to report event detection Integrated D+/D- Switches 2 and status changes. It also has an I C interface that the Moisture Detection/Corrosion Prevention system can use to read/write and configure internal regis- High Voltage V (28V) BUS ters. Short to V Protection on CC Pins (22V) BUS The IC has nine configurable GPIOs that can be used for Dead Battery Support detection, as interrupts, and as the enable/disable pin for Dual Supply Inputs from SYS and V BUS 2 external devices, or as ADC inputs. I C Programmable Configuration 2 I C Master to Control External Charger or Direct The IC is available in a 3.10mm x 2.65mm, 0.5mm pitch, Charge IC wafer-level package (WLP).
