24 / 46 page  • Ensure that each device’s CCFG pin is configured appropriately for its specific number of cells (three, four, or five cells). • For the bottom device, the CHG pin should be used to drive the CHG FET and leave the CHGU pin unconnected. For the upper device, the CHGU pin should be used to connect to lower device’s CTRC pin with a RCTRx and leave the CHG pin unconnected. • Connect the upper DSG pins with a RCTRx to the immediate lower device CTRD pin. • All upper devices should have the SRP and SRN to its AVSS pin. • If load removal is not used for UV recovery, connect the upper device LD pin to its AVSS pin, as shown in Figure 8-9 and Figure 8-10. Otherwise, refer to Figure 9-7 for proper LD connection. bq77905 RIN RIN RIN RSNS CIN CIN CIN RGS_CHG RGS_DSG RTS CVDD PACK- RLD RVDD RTS_PU RDSG RCHG CTRD AVDD VC5 VC4 VC3 VC2 DVSS TS LD CHG DSG CTRC CCFG SRP AVSS VC1 CHGU VTB SRN VDD CVDD RIN CIN CIN RIN bq77905 RIN RIN RIN CIN CIN CIN RTS CVDD PACK+ RVDD RTS_PU RCTRD RCTRC CTRD AVDD VC5 VC4 VC3 VC2 DVSS TS LD CHGU DSG CTRC CCFG SRP AVSS VC1 CHG VTB SRN VDD CVDD RIN CIN CIN RIN Figure 8-9. 10S Pack Using Two BQ77905 Devices BQ77904, BQ77905 SLUSCM3K – APRIL 2020 – REVISED JULY 2020 www.ti.com 24 Submit Document Feedback Copyright © 2020 Texas Instruments Incorporated Product Folder Links: BQ77904 BQ77905 |
