25-10-2023 | Littelfuse | Semiconductors

Littelfuse, Inc. has released the latest addition to the eFuse Protection ICs product line of versatile circuit protection devices, the LS0502SCD33. This pioneering innovation marks a noteworthy milestone in the industry, delivering the eFuse Super Capacitor Protection IC, a cutting-edge solution created specifically for backup power charging applications in harsh environments.

In many applications where backup power is critical, the narrow temperature range of Li-Ion batteries limits their use. To manage this challenge, the company developed a new supercapacitor-based solution that delivers a wide operating temperature range and high power/energy density, providing a safe and compact alternative.

One of the key differentiators of the device is its ability to handle high operating voltages (>3V) without the necessity for complex power management systems. The device safeguards the system from potential damage by integrating input overvoltage and current protection, providing designers with a flexible, integrated, and compact storage capacitor or capacitor bank backup solution. Furthermore, it features an ideal diode for reverse blocking when the input voltage is lost, enhancing its reliability and efficiency.

The eFuse Protection ICs are ideal for a wide range of SuperCap applications, including Dash cameras, Smart meters, IoT devices, Handheld industrial tools, and Portable gadgets with detachable batteries.

“The LS0502SCD33 eFuse provides electronics designers with a high-efficiency integrated SuperCap charging IC solution in a single chip,” said Bernie Hsieh, assistant product manager, Protection Semiconductor Business at Littelfuse. “This addition to our eFuse Protection ICs product portfolio expands the line’s solutions to include portable battery device protection, making Littelfuse a forerunner in the burgeoning market of management and protection for SuperCap applications.”
