Texas Instruments' TPS16530 provides comprehensive protection for a wide range of systems and applications powered from 4.5 V to 58 V. Equipped with a 31 mΩ integrated FET, this eFuse offers adjustable features, including accurate overcurrent protection, fast short-circuit protection, output slew rate control, and undervoltage lockout, ensuring robust safeguarding for the load, source, and the eFuse itself.
The Power Good (PGOOD) feature enables and disables control of downstream DC/DC converters, enhancing system efficiency and flexibility. Additionally, the enable pin allows external control for activating or deactivating the internal FET, while the shutdown pin facilitates low-power shutdown mode, optimizing power management.
Furthermore, the TPS16530 provides fault and precise current monitor output for system status monitoring and downstream load control, enhancing operational visibility and control. The MODE pin adds flexibility by enabling the configuration of the device between two current-limiting fault responses (latch-off and auto-retry), catering to diverse application requirements.
Available in 20-pin HTSSOP and 24-pin VQFN packages, the TPS16530 is designed to operate over a wide temperature range of -40°C to +125°C, ensuring suitability for various operating environments. Its user-friendly design, comprehensive protection features, and flexible configuration options make it an ideal choice for diverse system and application requirements.
