概览

The NCP81295 and NCP81296 are hotswap controllers with a low on resistance MOSFET (0.65mohms). These devices provide overcurrent protection during short circuit and overcurrent condition. It low on resistance reduces losses and the current is monitored by the internally current mirror, thus eliminating the need for a sense resistor, thereby saving power and cost. These devices can be paralleled for higher current conditions. Robust soft operating area performance helps minimize the number of paralleled device in higher current applications. The NCP81295 offers latch off during overcurrent while the NCP81296 offers hiccup operation. Both parts are offered in a thermally enhanced 5mm by 5mm QFN package.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
