Product Overview: LTC3625EDE#PBF from Linear Technology

The LTC3625EDE#PBF is a high-performance, dual supercapacitor charger manufactured by Linear Technology, now part of Analog Devices. This integrated circuit is designed to efficiently charge two supercapacitors in series from a single input supply. It is housed in a compact, low-profile (3mm x 4mm) DFN package, which makes it an excellent choice for space-constrained applications.

The LTC3625EDE#PBF features a programmable charge current up to 2A, which allows for rapid charging of supercapacitors with a wide range of capacities. The charging voltage is also programmable, with an accurate input supply range from 4.5V to 17V. This flexibility makes it suitable for a variety of industrial, automotive, and consumer applications where energy storage is critical.

One of the key benefits of the LTC3625EDE#PBF is its automatic cell balancing feature. This function ensures that both supercapacitors charge to the same voltage, preventing overvoltage conditions that could potentially damage the supercapacitors or affect their longevity. Moreover, the device offers a charge balancing status output that can be used to monitor the progress of the charge balancing process.

Safety features are an integral part of the LTC3625EDE#PBF design. The device incorporates overcurrent protection, thermal shutdown, and a programmable input current limit to safeguard the supercapacitors and the charging circuitry. Additionally, the quiescent current is minimal, which is ideal for battery-powered or energy-sensitive systems.

Overall, the LTC3625EDE#PBF is a robust and versatile supercapacitor charging solution that offers precision, efficiency, and reliability. Its comprehensive set of features and compact form factor make it a prime choice for engineers and designers looking to incorporate supercapacitor charging into their power management designs.
