FDMF3170
ON Semiconductor
Smart Power Stage (SPS) Modules with Integrated Current and Temperature Monitors
Package Type: PQFN-39
The FDMF3170 is ON Semiconductor’s next generation Smart Power Stage (SPS) solutions with fully optimized, ultra-compact, integrated MOSFETs with advanced driver IC current and temperature sensors, 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, system parasitic reduction, and power MOSFET R
DS(ON). The integration of Power MOSFETs with a driver IC also enables high accuracy module-level current and thermal monitoring. The FDMF3170 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 very accurate thermal monitoring (TMON) that provides a 0.8V output at 25°C with an 8 mV / °C slope.
