Part Number: BQ76940 Hi WM, I made connections as per fig 8.3 of datasheet bq76940 for 12s configurations. I gave boot signal of 3v to TS1 pin. After giving Boot signal i was able to observe CAP1, CAP2 and CAP3 pin voltage>3v. I checked REGOUT pin voltage wrt Vss and i observed it to be 300mV. i thought my source follower circuit is having some issue. So i gave 18.8v from 5th cell to regscr. Again i booted the device and checked volts across cap1,cap2 and cap3 >3v REGOUT pin to vss volt was gain 300mV. I tried checking for shorting across REGOUT pin and was able to observe low resistance of 45 ohms across this pin. I have another working board and i crossed checked its REGOUT pin to vss resistance and i observed it to be in Mohms. Can you suggest what can cause the regout pin to vss resistance to go low. I hope my RCA is in right directions. please find attach my circuit diagram with this for reference. Thanks Imran
