Hybrid Photovoltaic PMICs

Single-chip power management spanning microwatts (indoor) to watts (outdoor) for continuous device charging.

Hybrid photovoltaic power management integrated circuits (PMICs) combine solar energy harvesting with intelligent power management on a single chip, enabling devices to operate continuously by seamlessly transitioning between indoor and outdoor light conditions. These systems can harvest microwatts from indoor ambient lighting and scale up to watts from direct sunlight, automatically managing power flow to charge batteries, power devices directly, or store energy for later use.

The hybrid architecture intelligently switches between different power sources—solar, battery, or external power—optimizing energy usage based on availability and device requirements. Advanced power management algorithms maximize energy harvesting efficiency, manage battery charging cycles, and ensure stable power delivery. This enables truly battery-free or self-sustaining IoT devices, wearables, and sensors that can operate indefinitely in environments with sufficient light. Applications include outdoor sensors, wearable devices, smart home devices, and industrial monitoring systems where battery replacement is impractical.
