Analog Devices MAX77958 Product Info

The MAX77958 is a robust solution for USB Type-C CC detection and power delivery (PD) protocol implementation. It detects connected accessories or devices by using Type-C CC detection and USB PD messaging. The IC protects against overvoltage and overcurrent, and detects 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 contains V_CONN switches for USB PD and an enable pin for an external V_CONN boost or buck converter. When the USB PD negotiation is complete, the IC configures an alternate mode setting for external multiplexers.

The IC is compliant with USB Type-C Specification Release 1.3 and PD 3.0. It can be customized easily without affecting the compliance.

The IC has an I²C master that can read and write to other devices in the system so that its firmware can configure related 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.

The IC has an interrupt output pin to report event detection and status changes. It also has an I²C interface that the system can use to read/write and configure internal registers.

The IC has nine configurable GPIOs that can be used for detection, as interrupts, and as the enable/disable pin for external devices, or as ADC inputs.

The IC is available in a 3.10mm x 2.65mm, 0.5mm pitch, wafer-level package (WLP).

The IC is a highly customizable Power Delivery controller solution. Contact Analog Devices to check how the MAX77958 can be used for customer-specific use cases.
