Lumissil Microsystems is a fabless semiconductor company based in San Jose, California, specializing in the design, development and marketing of high-performance analog and mixed-signal integrated circuits. Its products serve automotive, IoT and industrial customers, with a goal of offering a diverse portfolio to meet various signal processing and control needs. Starting with LED drivers and audio amplifiers, Lumissil has expanded its lineup to include touch sensors, microcontrollers, MPUs, and power management and connectivity technologies. Because the company operates without its own fabrication facilities, it relies on established relationships with key semiconductor foundries to deliver innovative and cost-effective analog solutions while helping ensure supply continuity for its customers. Lumissil emphasizes long-term relationships and aims to be a reliable long-term supplier. In 2026 Lumissil announced the launch of a high-voltage, dual-channel LED lighting controller for 48V automotive systems.
