Denison M6F Series M6F3N1D0 M6F3N M6F3N1D M6F3N1D3

Denison hydraulic plunger pump VDD is the control supply and it provides power both to input logic and to output power stage. Input logic is referenced to COM ground. The under-voltage circuit enables the device to operate at power on when a supply voltage of at least a typical voltage of VDDUV+ = 10.4V is present. The IC shuts down all the gate drivers power outputs, when the VDD supply voltage is below VDDUV- = 9.4V. This prevents the external power switches from critically low gate voltage levels during on-state and therefore from excessive power dissipation

VB(U,V,W) and VS(U,V,W) (High side supplies) VB to VS is the high side supply voltage. The high side circuit can float with respect to COM following the external high side power device emitter voltage. Due to the low power consumption, the floating driver stage is supplied by integrated bootstrap circuit. The under-voltage detection operates with a rising supply threshold of typical VBSUV+ = 10.41V and a falling threshold of VBSUV- = 9.4V. VS(U,V,W) provide a high robustness against negative voltage in respect of COM. This ensures very stable designs even under rough conditions. N(U, V, W) (Low side emitters) The low side emitters are available for current measurements of each phase leg. It is recommended to keep the connection to pin COM as short as possible in order to avoid unnecessary inductive voltage drops. VTH (Thermistor) A UL certified NTC is integrated in the module with one terminal of the chip connected to COM and the other to VTH. When pulled up to a rail voltage such as VDD or 3.3V by a resistor, the VTH pin provides an analog voltage signal corresponding to the temperature of the thermistor
