Overview
Description
A supercapacitor, also known as an electrical double-layer capacitor (EDLC), has features such as short charging time, high power density, long lifecycles, good temperature performance, and environmental protection. EDLCs can replace traditional batteries, which are prone to issues like electrolyte leakage, as a reliable backup power supply. They provide power for data backup and wireless communication during short power outages.
Renesas' smart power meter system integrates 4G communication and EDLC technology to enable smart control and always-on functionality. The buck-boost regulator enables self-cycling EDLC backup and can discharge the EDLC voltage down to 0.1V (theoretically), maximizing efficiency and reducing system cost. Additionally, the ultra-low-power MCU is ideal for measurement devices and power meters, featuring a built-in segment LCD driver for enhanced functionality.
System Benefits:
- Maximizes the power of supercapacitors with a buck-boost regulator capable of discharging down to 0.3V
- Features a low-cost 16-bit MCU with ultra-low power consumption and a built-in segment LCD driver
- Provides an optimized design for battery and EDLC-based always-on systems, ensuring reliability and cost efficiency.
