Other Parts Discussed in Thread: LSF0102
So I designed my low power board and I discovered that the TS5A2066 circuit consume a lot of current. When I tried to de-solder the TS5A2066 circuit from my board the current consumption dropped to a normal value. The current dropped 1mA.
So I have a microntroller which works with 2.5v volts and I have two signal that the microcontroller should read, but these signal use directly the battery voltage and have a higher voltage of a 3.3V and can reach 4.2v all depend on the battery level.
this is why I used the TS5A2066 circuit , in order to convert the 3.3v-4.2v to a 2.5v thus the microcontroller can read it.
Here's the schematic of the circuit that I made.
So as you can see I use for the circuit power supply 'V+' the battery voltage, which can vary from 3.2v to 4.2v all depend on the battery level.
The signal CHARGER_STAT and VinOK are the two signals that I want to convert their level. These two signal use the same voltage level as the V+ which is the battery voltage.
In the two COM pins I put the 2.5v regulated voltage which is the same voltage that the microcontroller use.
And finally the NO pin I connect them to the microcontroller.
I don't know if I forgot something, or something is wrong here but the circuit consume a lot of current as it supposed to be.
In addition of that I think that the circuit behavior is not correct.
I'm wondering if I had to switch between the NO et COM pins ? The COM pin should be connected to the microcontroller and the NO pins should be connected to the 2.5v ?
is the current orientation matter in this circuit ?
please give me suggestion to get rid of this issue
