Intelligent Power Switching SoC Framework

Programmable mixed-signal power switching SoC framework
for automotive and industrial applications

The Intelligent Power Control SoC Framework is an engineering platform designed to address the needs of the automotive and industrial semiconductor design.

Structured around a 6-channel mixed-signal implementation, the framework integrates power-stage control, sensing, diagnostics, protection, and programmable RISC-V-based supervision. It provides the engineering teams at eInfochips with a practical environment in which to develop, validate, and demonstrate the expertise necessary to support customers across complex, application-specific semiconductor programs.

The framework has been implemented on the GlobalFoundries’ GF130BCD process, providing a silicon-backed foundation for automotive and industrial mixed-signal ASIC development.

The framework can also be offered as a customized IP or as a ready-to-use reusable AMS subsystem component within the customer’s chip-development programs.
