onsemi — NIS4461 Series eFuses

onsemi NIS4461 series of resettable electronic fuses extends its portfolio of eFuse products, providing cost-effective circuit protection for motors, power supplies and other applications that have a maximum input voltage of 30V.

onsemi’s resettable eFuses have a programmable current limit and include integrated over-current, over-temperature, over-voltage and reverse-current protection. Signals for fault reporting and for disabling the output may be transmitted via general-purpose I/Os.

The NIS4461 buffers the load from excessive input voltages which could damage sensitive circuits.  It includes an over-voltage clamp circuit which prevents voltage spikes from reaching the load while allowing the load circuit to continue operating.

The NIS4461 offers a choice of operating modes when triggered, either latch-off, or auto-retry for restarting.
