Overview

The FDMF5075 is onsemi’s next generation of Smart Power Stage (SPS) solutions with fully optimized, ultra−compact, integrated MOSFETs plus driver for high−current, high frequency, and synchronous buck DC−DC converters.
With an integrated approach, the SPS switching power stage is optimized for driver and MOSFET dynamic performance, minimized system inductance, and power MOSFET RDS(ON).
The integration of Power MOSFETs with a driver IC also enables advanced high accuracy module thermal and current monitoring. The FDMF5075 provides an output signal (IMON), which reports the real−time module current. IMON is a very accurate, 5 μA/A signal representing the real time Power MOSFET drain currents. The IMON signal can be used to replace inductor DCR current sense or resistor sense methods.
The FDMF5075 also includes very accurate module thermal monitor (TMON). TMON is a voltage sourced PTAT signal that is calibrated to provide a 0.8 V output at 25°C with an 8 mV / °C slope.

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.)
