Part Number: TPS650732 Other Parts Discussed in Thread: TPS65072 , TPS65217 Hi Teams,
My customer is looking for a PMIC with lithium battery charging management IC, which requires support for 2 DC-DC (between 3.3V output and 3.4-4.2V output)+at least…
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…
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…
Information written into the TPS650732 internal registers is erased when power is removed from VCC. This information must be rewritten at power up. The IC does not have non-volatile registers available for the customer.
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…
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.
Other Parts Discussed in Thread: TPS650732 , AM3517 I am trying to write to the TPS650732 PMU from an AM3517 CPU. The AM3517 seems to program fine--we have several other functions on the board functioning properly. BUT, our I2C CLK frequency is supposed…
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…
