11 / 58 page L6751B Pin description and connection diagram Doc ID 024028 Rev 1 11/58 27 SCSP A Single-phase section current senses positive input. Connect through an R-C filter to the phase-side of the channel 1 inductor. 28 SCSN A Single-phase section current senses negative input. Connect through an Rg resistor to the output-side of the channel inductor. Filter the output-side of Rg with 100 nF (typ.) to GND. 29 SIMON A Current monitor output. A current proportional to the single-phase current is sourced from this pin. Connect through a resistor RSIMON to GND. When the pin voltage reaches 1.55 V, overcurrent protection is set and the IC latches. Filtering through CSIMON to GND allows the delay for OC intervention to be controlled. 30 DPM4-6 A Connect a resistor divider to GND/VCC5 in order to define the DPM and GDC strategies. See Table 11 and Table 12 for details. 31 SRGND A Remote buffer ground sense. Connect to the negative side of the single-phase load to perform remote sense. 32 DPM1-3 A Connect a resistor divider to GND/VCC5 in order to define the DPM and GDC strategies. See Table 11 and Table 12 for details. 33 SFBR A Remote buffer positive sense. Connect to the positive side of the single-phase load to perform remote sense. 34 SVSEN A Remote buffer output. Output voltage monitor, manages OV and UV protection. Connect with a resistor RSFB // (RSI - CSI) to SFB. 35 SFB A Error amplifier inverting input. Connect with a resistor RSFB // (RSI - CSI) to SVSEN and with an (RSF - CSF)// CSH to SCOMP. 36 SCOMP A Error amplifier output. Connect with an (RSF - CSF)// CSH to SFB. The device cannot be disabled by pulling low this pin. Table 2. Pin description (continued) Pin# Name Type Function |
