Resettable fuse
19 February 2014
Circuit & System Protection
For hot-plug consumer and industrial products, including external disks, printers and servers, the NIS5132 resettable electronic fuse from Diodes Incorporated helps 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 a wide input voltage range from 9 V to 18 V, and provided in the small, low-profile DFN3030-10 package, the 3,6 A rated device integrates a low on-resistance NMOS buffer and an internal current limit. With the buffer’s typical
RDS(ON) of only 30 mΩ and with no need for an external sense resistor in the load path, the device minimises voltage drop and power loss.
To fully safeguard downstream power components from damage or premature ageing, 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).
