Can I use two MAX40203 ICs in an ORing configuration?

Yes you can use two MAX40203 ideal diodes in an ORing configuration, where the voltage of either input supply does not exceed the maximum rating of 6V. The "load" side of the MAX40203 will see whichever…
Does the MAX40203 have any reverse battery protection?

The MAX40203 does not provide protection against a battery being connected incorrectly. This IC is designed for positive voltages only. We assumed that the battery is always inserted correctly. One…
MAX40203 can V_enable be greater than VDD?

Yes, the V_enable pin can be greater than VDD, but observe the 6V absolute maximum voltage for all pins. There is an extra current draw to ground associated with this, called I_EG in the datasheet electrical…
Question about MAX40203 EN pin.

Q: What is the input impedance for the EN pin of MAX40203? In our application, input voltage is 3.6V. Pull up with 10Mohm resistor. The voltage measured on EN pin is 2.0V. The output voltage is 3.6V. Is…
What are the anode current & cathode current for MAX40203?

Q: For MAX40203, it could operate in reverse mode when Vout>VDD (Threshold 26mV). But in datasheet, it has both anode current & cathode current both, why & what are they. A: When the chip operations…
