Other Parts Discussed in Thread: TPS3823,
Hello,
Can you pls. clarify how to start up the TPS65070 to achieve the following things:
Note: I don`t use a possibility of turning TPS65070 on and off using a button.
My application is such that should not require an ON-key but shall power-up automatically once supply voltage is applied.
The device must do the following things:
1. Turn ON from USB/AC when there are USB/AC supply and LiPo Battery charging.
2. Turn ON from Li-Ion battery when there is no USB/AC supply.
3. Should Work until battery will be discharged (VBAT < VUVLO) when there is no USB/AC supply.
4. Should automatically turn ON the system(Load) when AC/USB again get plugged while charging the battery on one hand.
How should be the PB_IN# and POWER_ON hardware and software configuration??
Please let me know what should be done to make the above function done?? How should be the hardware connection?? How can we make it possible without using any external hardware other than Microcontroller which has to be powered from the TPS65070 only?
I have gone through this thread, did it work??:
Thanks in advance.
