Excuse me,I have designed a solar panel(6v/15mA) connected to adum6010,but it didn't work.why?
When I use a solar panel(6v/15mA) to connect adum6010,I measured input voitage.
It is down to 2v, even lower.how come?
to put it simply: the ADUM6010 will take as much input current as it needs, to generate the desired output power. So if you are afraid of too much current, make sure that your output-load is not demanding more power than the ADUM can deliver.
If you are afraid, that the input voltage might get too high, then you could indeed add some protection (a 5,6V Zener diode at the ADUM6010 input would be a simple solution).
As your circuit is running well with a power supply, but not with the solar cell, you might consider the following. The solar cell will only deliver its nominal power under certain conditions. Did you test your setup in bright daylight? If you tested it inside a room, the solar cell will only deliver a small fraction of its nominal power. Even if its irradiated by a normal light bulb, the delivered power might be much to small to drive the ADUM.
1. 6V is within the Absolute Max Ratings, but recommended is 5V as input voltage max. - for this the full specification is valid.
2. what is your connected output load on the Viso ? As the efficiency of he ADuM6010 is 29%, you need approx. 3.5 times higher input current.
Can you provide a schematic or block-diagram of your configuration?
You mean that the current is not high enough? but datasheet doesn't show the range of the input current?
but i have tried another solar panel(5.5v/85mA) it still didn't work.
My connected output load on the Viso is Super Capacitor.
The super-cap has uncharged a low input impedance, so the current require may be too high for the solar panel. As requested, can you provide a block-diagram or schematics?
But I haven't use adum6010 output to connect super-cap,i just use ammeter to measure the output voltage of adum6010.
You may need to have a min. load on the output.
But it would be better to have a schematic or block-diagram to help you more efficient.
like this, then i use ammeter to measure the output voltage.
before this.i have used Power Supply to simulate,it can work
Are you sure the solar cell is able to delivering 15mA without the ADuM6010?
Have you checked with a ampmeter?
Have you checked the ADuM6010 operation with another voltage source, that is operating correctly?
.I have used Power Supply to simulate,ADuM6010 is operating correctly.
so my problem is that the current is too low?
I'm afraid too much current,ADuM6010 would be damage.
What current has been flowing into the ADuM6010 as you tested it with the PSU?
To limit the current into the ADuM6010 you may use a serial resistor!?
