Overview

The NCP339A and NCP339B are very low Ron MOSFETs controlled by an external logic pin, allowing optimization of battery life, and portable device autonomy. Indeed, thanks to a current consumption optimization with PMOS structure, leakage currents are eliminated by isolating connected IC on the battery when not used.Reverse blocking control is automatically engage if OUT pin voltage is higher than IN pin voltage, eliminate leakages current from OUT to IN. NCP339B is available with output autodischarge function when part is disable.

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

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.)
