To support a range of applications, the e-fuse, rated at 3.6A, has been designed to operate over an input voltage range of 3.1 to 18V. The NIS5135 integrates an NMOS power device with 30mO RDS(ON). It also features an internal current limit that is said to avoid 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. The device also includes a dv/dt control and thermal shutdown circuits, with latching (NIS5135MN1) or auto-retry (NIS5135MN2) options.
Supplied in a 3 x 3mm, low profile U-DFN3030-10 package to minimise application footprint, the NIS5135's industry-standard pin-out allows it to be implemented into existing designs.
