Si115x seen at power down? on
Sensor IC Forum
What impedance will the LED pins have when the circuit is shut down?
What occurs with the LED contribution on the Si115x if the force supply to the circuit is closed off when the IR-LED actually is controlled from the battery.
Is there a danger for current spillage through the LED that chat avenue ultimately could deplete the battery, if so how huge would that spillage be?
Or then again is the plan of the current sink controller done so a high impedance is ensured?
In the present circumstance is it prescribed to have the draw-up resistors associated with the managed power space which Si115x is controlled from or is there any motivation to have the resistors associated straightforwardly to the battery together vid the LED?
