The FDMF5176 is ON Semiconductor’s next generation of Smart Power Stage (SPS) solution 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 FDMF5176 provides an output signal (IMON), which reports the real−time module current. The IMON signal can be used to replace inductor DCR current sense or resistor sense methods. There is also accurate thermal monitoring (TMON) that provides a 0.8 V output at 25°C with an 8 mV / °C slope.
