35A Smart Power Stage (SPS) Modules with Integrated Current and Temperature Monitors

Overview

The FDMF5076 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 FDMF5076 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 FDMF5076 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.
