11 / 57 page  DocID025037 Rev 1 11/57 L6751C Pin description and connection diagrams 57 A14 SCSP A Single-phase section current senses positive input. Connect through an R-C filter to the phase-side of the channel 1 inductor. B13 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. A15 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. B14 DPM4-6 A Connect a resistor divider to GND/VCC5 in order to define the DPM and GDC strategies. See Table 11 on page 24 and Table 12 on page 26 for details. A16 SRGND A Remote buffer ground sense. Connect to the negative side of the single-phase load to perform remote sense. B15 DPM1-3 A Connect a resistor divider to GND/VCC5 in order to define the DPM and GDC strategies. See Table 11 on page 24 and Table 12 on page 26 for details. A17 SFBR A Remote buffer positive sense. Connect to the positive side of the single-phase load to perform remote sense. B16 SVSEN A Remote buffer output. Output voltage monitor, manages OV and UV protection. Connect with a resistor RSFB // (RSI - CSI) to SFB. A18 SFB A Error amplifier inverting input. Connect with a resistor RSFB // (RSI - CSI) to SVSEN and with an (RSF - CSF)// CSH to SCOMP. D3 SCOMP A Error amplifier output. Connect with an (RSF - CSF)// CSH to SFB. The device cannot be disabled by pulling low this pin. A19 IMAX / SIMAX A Connect a resistor divider to GND/VCC5 in order to define the IMAX and SIMAX registers. See Table 8 on page 21 and Table 6 on page 20 for details. Table 2. Pin description (continued) Pin no. Name Type Function |
