  • BQ75614-Q1: BQ75614-Q1: BQ75614 communication loss in negative temperature

    Part Number: BQ75614-Q1 Hello Nate, Please find attached the LDOIN, DVDD, CVDD, AVDD measurements at LT. DVDD, CVDD, AVDD are stable. Regarding LDOIN, a voltage drop to 5.908 V was observed when U_BAT = 44 V, when U_BAT=20V LDOIN variates bteween…

  • BQ75614-Q1: BQ75614 with electric hot plug

    TI Thinks Resolved
    Part Number: BQ75614-Q1 Hello everyone ,What functional abnormalities will occur to the BQ75614 chip if it undergoes hot swapping, and which of these abnormalities are most likely to trigger

  • BQ75614-Q1: BQ75614 communication loss in negative temperature

    Part Number: BQ75614-Q1 We are observing sporadically DVDD undervoltage (SM007) and Sometimes UART Communication loss at around -22degC. What could be the reason for this behaviour and is there any fix for this issue? Please reach out to me in case of…

  • BQ75614-Q1: BQ75614-Q1: The impact of frequent resets on the chip

    Part Number: BQ75614-Q1 Hi TI experts, I would like to inquire about the impact of frequent resets on BQ chip. After each communication failure, the MCU will reset the BQ chip through WAKE Ping to restore communication. Due to frequent communication…
