Part Number: TPS650732 I have the exact same issue as in the linked question. The PMIC powers on the first time after the battery is connected by pulling PB_IN low. POWER_ON is pulled up to the output of DCDC1 to keep the PMIC on. Then, when POWER_ON…
Other Parts Discussed in Thread: TPS650732 , AM3505 My customer has two questions on the charger of the TPS650732.
①
I want to know about the charger function of TPS650732. Is it possible to charge up when CPU (AM3505) is not working?
Furthermore, is…
To be able to
initiate a system-wide (board level) Reset (shutting down all the voltage besides Vsys and
AC), is it best to that with a pushbutton switch on /PB_IN, PB_OUT, or POWER_ON? I currently have POWER_ON pulled high to Vsys
so I don’t believe…
Other Parts Discussed in Thread: TPS650732 My customer has a question on the PGOOD delays of the TPS650732. They want to speed up the boot up in their application and want to change the default delay from 400mS to 100mS or possibly 20mS. If they intend…
Other Parts Discussed in Thread: TPS650732 In our application, we like all the features of TPS650732, like power path management, three step-down DC/DC, battery charger and wLED booster converter etc. But the power sequence of TPS6505x and TPS65073x don…
Part Number: TPS65070 Other Parts Discussed in Thread: TPS65072 , TPS650732 , TPS650731 , TPS65073 How should I connect/terminate un-used pins on the TPS65070?
The TPS65070 shares a datasheet with the TPS65072, TPS65073, TPS650731, and TPS650732. Does this…
Other Parts Discussed in Thread: TPS650732 , AM3517
I put a switch in to pull POWER_ON (from the TPS650732) low (it is
otherwise pulled up to Vsys). I would still like to tie POWER_ON to the
AM3517, though, in order to give the 3517 the ability to reset…
That was my mistake. I was referring to the TPS650732 PMIC from TI. I've sinced learned that I do NOT need the battery hooked up to the "AC" pin on the PMIC.
Sorry, I think it is not clear, just understand that it needs to modify, but where and modify what? Please point out. What's the diff with TPS65023? Since TPS650732 this chip may be use for touch, LED backlight driver, it is important. Thanks.
