Resettable fuse enhances system reliability
Targeted at hot plug consumer and industrial products, including external disks, printers and servers, the NIS5132 from Diodes is designed to raise power system reliability by protecting against shutdown and catastrophic failures.
By allowing a product to restart, the device enables a reduction in unnecessary field returns.
Operating over an input voltage range from 9 to 18V, and provided in a small, low profile DFN3030-10 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 30mO and with no need for an external sense resistor in the load path, Didoes says the device minimises 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.
The thermal shutdown can be either latching type (NIS5132MN1) or auto-retry type (NIS5132MN2).
