Rutronik is now stocking the NIS5132 resettable electronic fuse from Diodes. Suitable for hot plug consumer and industrial products, including external disks, printers and servers, and helping to raise power system reliability by protecting against shutdown and catastrophic failures the device has been designed to allow products to restart enabling a reduction in unnecessary field returns.
Operating over a wide input voltage range from 9V up to 18V, and provided in a small, low-profile DFN-3030-10 package, the 3.6A-rated NIS5132 integrates a low on-resistance NMOS buffer and an internal current limit. With the buffer”s typical RDS(ON) of only 30mOhm and with no need for an external sense resistor in the load path, the device is able to minimise voltage drop and power loss.
To fully safeguard downstream power components from damage or premature aging, the fuse”s protection features include under-voltage lockout, turn-on ramp control, current-limit and thermal shutdown circuits. This thermal shutdown can be either latching type (NIS5132MN1) or auto-retry type (NIS5132MN2).
