Description

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 up during overcurrent while the NCP81296 offers hiccup operation.Both parts are offered in a thermally enhanced 5mm by 5mm QFN package.
