Other Parts Discussed in Thread: MAX3232

Hi Team,

The supply current of MAX3232 shows 0.3mA(TYP) at condition of "No load".

Is there any supply current data "With load" (for example RL=3～7kΩ to GND) just for reference?

The relationship between ICC current and DOUT current is 2:1 for 5V and 2.3:1 for 3.3V.
For a 5k load and 5.4V DOUT voltage, 1.08mA will flow per channel.
So for 3.3V VCC, typical ICC will be 0.3mA + 2 * 1.08mA * 2.3 = 5.3mA
