Self-Protected Resettable e-Fuse from Diodes Incorporated Targets Consumer Applications

Diodes NIS5135

Diodes Incorporated introduced the NIS5135. Designed to enhance system reliability against shutdown and catastrophic failures, this resettable electronic fuse is well-suited for plug and play applications in consumer applications including hard disc and solid state drives, printers, and set-top boxes. By allowing the product to recover, this e-fuse helps reduce unnecessary field returns.

Operating over a wide 3.1 V to 18 V input voltage range and rated at 3.6 A, the NIS5135 integrates an NMOS power device with a low 30 mΩ RDS(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 small, low profile U-DFN3030-10 package to minimize application footprint, the NIS5135’s industry-standard pin-out allows it to drop into existing designs, providing an alternative lower-cost source for high volume production.
