Power MUX IC - 12V, 15A

Reference Designs
1

Hi,

We are design carrier board having two input power rails.

We are looking for a IC that can automatically switch the power rails based on the priority setting.

Input Voltage : 12-24V DC (Both rails)

Output Current : 15A

Please let me know if there any IC suits our requirement?

Or suggest any circuit that works for our requirement?

Perhaps using the MPQ5850 ideal diode controller could be used in OR logic where you could program conditions to switch between these two rails would be helpful.

The input voltage for this IC ranges from 3.3V - 36V, external FETs could be implemented to size up to 15A, and a comparator can be used for priority logic to enable this OR logic.

Here is the typical application and link to the IC listing for your convenience:

MPQ5850-AEC1 | 36V, Smart Diode Controller with Reverse Protection, AEC-Q100 Qualified | MPS

Let me know if there are any follow up questions.

Best,
Krishan
