STMicroelectronics ST-ONEMP Integrated Controller for Multi-Port Chargers
Discover the STMicroelectronics ST-ONEMP PMIC, the world’s first digital controller with ARM Cortex M0+, offering advanced power management features.
The STMicroelectronics ST-ONEMP power management integrated circuit (PMIC) is claimed as the world’s first digital controller with embedded ARM Cortex M0+ core, offline programmable controller with synchronous rectification, and USB PD PHY in a single package. Within the package is an active clamp flyback controller on the primary side, and a microcontroller and USB-PD communication on the secondary side. The two sides are connected through embedded galvanic isolated dual channel communication.
This report presents a power essentials analysis of the STMicroelectronics ST-ONEMP PMIC. The analysis includes structural and materials analysis, and critical dimensions, providing information and insights into the design and process attributes that may relate to performance. Additionally, foundry and node identification are also provided.
