The MIPI System Power Management Interface (SPMI) is a standardized hardware interface designed to connect power management controllers with various peripheral components. It is a critical specification for modern mobile devices, wearables, and IoT hardware where battery life and thermal efficiency are paramount.
If you're interested in learning more about the MIPI SPMI specification, you can download the official specification document from the MIPI Alliance website. The document provides detailed information on the interface, including its architecture, protocol, and implementation guidelines. mipi spmi specification pdf
Two-Wire Interface: Uses a serial data (SDATA) line and a serial clock (SCLK) line to minimize pin count. The MIPI System Power Management Interface (SPMI) is
