Hi,
I have mounted a pcb with the bq25504 module and everything works fine except the VBAT_OK signal. I have attached the bat_ok signal to the enable pin of a tps78233 ldo. It is supposed that it should enable the ldo when the bat voltsage (lipo battery) reach the bat_ok threshold but the ldo is never enabled: I have revised the boards (I have mounted two and both have the same problem) to look for possible shorts with no results. Have you got any idea of the cause of this issue?
I attach a schematic of the circuit
Thanks in advance.(Please visit the site to view this file)
