ADIMAX77958EWV+T
Overview
The MAX77958EWV+T is a standalone USB Type-C and USB Power Delivery (PD) controller designed to simplify the implementation of modern charging interfaces. It features an autonomous state machine that handles Power Delivery 3.0 negotiation without requiring an external microcontroller for basic operation. The device is housed in a compact 30-bump WLP package, making it suitable for space-constrained mobile and portable designs.
Why Choose This Part
The MAX77958 allows for faster time-to-market by using a firmware-less configuration approach via an autonomous state machine. It operates across a wide supply voltage range of 2.5V to 20V and features a low supply current of 192uA, optimizing energy efficiency in battery-powered applications. Its integrated BC1.2 detection and high-voltage VCONN switch reduce external component count and PCB footprint.
Applications
Key Specifications
Getting Started
Engineers can evaluate this controller using the MAX77958EVKIT, which provides a complete environment for testing PD negotiation and I2C communication. Configuration is typically handled through the Maxim Integrated GUI or by writing to internal registers over an I2C interface. Ensure the WLP footprint is designed with 0.5mm pitch layout rules to accommodate the 30-bump 2.62x3.07mm package.
