Hi Manuel,
I don't believe you can dismiss the 3.3V input on the TPS3514. Have you looked at TPS3779/80? These parts are dual channel voltage detectors with high accuracy.

Dan,
This functionality isn't internally supported by any of our supervisors. We will probably need to use 2 separate supervisors to achieve this functionality. One to mange each of the inputs, as using a dual channel won't allow one to be toggleable…
Hello Oliver,
One way to do this is my using a voltage supervisor and similar to the TPS3779 to control a FET placed in between the OUT pin of the charger and the system load.
Part Number: TPS3307 Other Parts Discussed in Thread: TPS3779 , TPS386040 , Hi,
do you recommend the TPS3307-33DR for a new industrial design or is there an alternative that is similar and newer?
Thanks

Part Number: TPS3780 Other Parts Discussed in Thread: TPS3779 Hi,
As described in the datasheet, for Early Warning Detection, TPS3779 is recommended. However, I am thinking of using TPS3780 because I need the output high logic level at 4.2V which is greater…
Hi Dick,
If you are able to generate the three distinct voltages like you state, I agree that it looks like TPS3700 could be a good fit. TPS3779 may also work if you do not mind a slightly different logic (take a look at the Early Warning Detection…
Part Number: TPS3806I33-Q1 Other Parts Discussed in Thread: TPS3779 , TPS3710 I am working with an TPS3806I33DBV. I am having trouble with the voltage drops across the Hsense and Lsense. In the order that they are shown in relevance to the resistor dividers…
