Self-protected resettable 3.6A e-fuse for consumer products

June 17, 2015 // By Graham Prophet
For improved reliability against shutdown and catastrophic failures, the NIS5135 resettable electronic fuse from Diodes Inc. is suited to plug and play applications in consumer applications including hard disc and solid state drives, printers, and set-top boxes.

Operating over a 3.1V to 18V input voltage range and rated at 3.6A, the NIS5135 integrates an NMOS power device with 30 mΩ R DS(ON) for reduced power loss. It also features an internal current limit that avoids the voltage drop normally incurred by an external sense resistor in the load path. An over-voltage circuit limits the output voltage without shutting the device down, while downstream components are further protected from damage or premature failure by under-voltage lockout (UVLO) and thermal shutdown circuits, with latching (NIS5135MN1) or auto-retry (NIS5135MN2) options.

Supplied in a low profile U-DFN3030-10 package to minimise application footprint, the NIS5135’s standard pin-out allows it to drop into existing designs, providing an alternative lower-cost source for high volume production. NIS5135 is priced at $0.39 (10,000).
