Other Parts Discussed in Thread: TDA4VM
Tool/software:
Hello
we use PDN-1A power solution for our product with TDA4VM, so we have TPS65941213RWERQ1 on board with the OVP protection (FET). The function is that input voltage ramps up (3.3V) then there is a delay (tVSYSOVP_INIT) and then PMIC turns on the FET by OVPGDRV pin. The FET turn on time is relatively fast which creates relatively high inrush current (our product has 5V input voltage -> 3.3V regulator -> PMIC with OVP, inrush current is 2A at 5V input in our case) which is a complication for us a bit. So I wonder if there is any possibility to change the FET turn on time (output slew rate), it means slower output ramp up, I didn't find anything in datasheet but please let me know. Thanks a lot!
Best regards
Libor
