In the below image, the output low voltage on the STATx pin is given as 1V. But that is for 4mA of sink current. Which translates to around 0.25ohm of internal resistance/impedance.
If the LED's forward current (LEDs connected to the STAT pins) is higher than the 4mA, then subsequently, the maximum output voltage on the STAT pins, would increase? How high can the output voltage go or be? Just want to understand how this works if the LED current is higher.
The word sink implies current flows into the pin. Indeed page 2 has a schematic showing pins 6-7-8 with led's connected, oriented with their other end connected to a positive supply.
Each has a 470 ohm resistor inline so it limits current going into the IC.
