FDMF3172: Intelligent Power Module (IPM) with Integrated Current and Temperature Monitors
Description: The FDMF3172 is the next generation of Intelligent...
The FDMF3172 is the next generation of Intelligent Power Module (IPM) 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 FDMF3172 provide 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 output filter inductor DCR current sense or resistor sense methods.
The FDMF3172 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.
