Part Number: TPS65217 I designed a custom pcb using Beaglebone black designs and pmic's datasheets. I powered the pmic from the AC and USB pins, and when there is a fluctuation in input power or if the power goes off for 1-2 seconds, the pmic crashes…
Part Number: TPS65217
I am using TPS65217C on my board and I have used the Beagle bone black as my reference. I am using Li-Ion battery to power the system and will get charged simultaneously. To increase the efficiency I changed the UVLO to 2.73V and…
Part Number: TPS65217 Hi
I am using Beaglebone Black which has TPS65217C PMIC. Using beaglebone black for battery operated application. For that we want to use lowest power consumption mode of operation.
I made power LED off by disabling LDO2 of TPS65217C…
Hi Ertugrul,
Is the battery connected to anything else in the circuit besides the PMIC?
OFF state input current should typically be 6 uA at room temperature according to the datasheet:
I just checked this on our TPS65217DEVM and I confirmed the 6uA spec…
Part Number: TPS65217 Other Parts Discussed in Thread: TL5209 Hi everyone,
I am using TPS65217C on my board and I have used the Beagle bone black as my reference. I am using Li-Ion battery to power the system and will get charged simultaneously.

Hi Jackson,
I just want to echo what James said - the top marking does not indicate any difference in the silicon revision. This is just a different lot trace code. It is very important to do a proper ABA swap in this type of situation to verify whether…
Hi James,
Thank you for your reply. Red color of the box in the top right corner od the app I called "red flag" for lack of better word.
To summarize what I have learned so far:
1. Any TPS65217x can be reprogrammed.
2. IPGUI doesn't verify at…
Part Number: TPS65217 Hello, can you explain why using RLL (10k Ω) instead of BAT pin capacitors can prevent the chip from entering a locked state? I want to know the specific reason why this action is effective?
In fact, I conducted validation…
Part Number: TPS65217 Hi,
I have a TPS65217C design that used the Beagle Bone as a reference design. In the reference design, the PMIC_EN pin is attached to the processor with no pull up resistor outside of the PMIC and that works well. I have a similar…
Part Number: TPS65217 Other Parts Discussed in Thread: TL5209 , Good afternoon!
I am verifying a PCBA design with an OSD3358-512M-ICB C-SIP. This SOM contains a TPS65217C PMIC, TL5209 LDO, and an AM355x Sitara processor. It is my understanding that the…
