HMI announced the release of the HL8520E, a state-of-the-art hot-swapable/e fuse device that provides superior protection and power control for sensitive load circuits.
The device protects the system from input transients, short circuits, and voltage spikes that can damage load circuits, while managing power delivery to improve reliability. It has an input voltage range of 2.7V to 16V, supports low and high voltage systems, and is suitable for a variety of applications. The device can also handle output currents up to 20A, providing reliable performance under heavy loads and making it ideal for power-intensive applications.
The device features an integrated low-RDS (on) MOSFET with a resistance of only 2.8mOhm, minimizing conduction losses and improving power efficiency and thermal performance. It includes a comprehensive set of protection features such as overcurrent protection, short circuit protection, thermal shutdown, damaged MOSFET detection, overvoltage protection and undervoltage locking to protect equipment and loads from electrical failures.
The device allows externally adjustable soft start, making the system run more smoothly and easy to control surge flow during startup. It also provides configurable current limits, providing further flexibility in power management and helping to ensure safe and reliable operation. Short circuit protection has a fast response time of less than 200ns, ensuring that the device quickly detects and mitigates fault conditions, minimizing system outages.
The device includes E-Fuse health reports that provide valuable diagnostic feedback for system monitoring and maintenance. The device is available in a compact LGA-26 package (4mm x 4mm), making it ideal for space-constrained applications where efficient use of board space is critical.
Mason Choi, Vice President/General Manager of HMI, said: "The HL8520E is ideal for a wide range of applications, including servers, hot swappable systems, laptops and disk drives. Its versatile design and robust protection make it ideal for environments where reliable power management and load protection are critical."
