Smart Power Stage (SPS) Modules with Integrated Current and Temperature Monitors

Favorite

Overview

The FDMF5071 is ON Semiconductor’s next generation SmartPower Stage (SPS) solution with fully optimized, ultra−compact,integrated MOSFETs with advanced driver IC current and temperaturesensors, for high−current, high frequency, and synchronous buckDC−DC converters.
With an integrated approach, the SPS switching power stage isoptimized for driver and MOSFET dynamic performance, systemparasitic reduction, and power MOSFET RDS(ON).
The integration of Power MOSFETs with a driver IC also enableshigh accuracy module−level thermal and current monitoring. TheFDMF5071 provides an output signal (IMON), which reports thereal−time module current. The IMON signal can be used to replaceinductor DCR current sense or resistor sense methods. There is alsoaccurate thermal monitoring (TMON) that provides a 0.8 V output at25°C with an 8 mV/°C slope.
