TPS2557-Q1: Pin 2 or 3 open; pin 6 or 7 open

Billyjoe Pecson

Part Number: TPS2557-Q1

Hello,

since Pin FMEA of the device mentioned is not available,

May I confirm if either one of the two input pins are open, the device will still work perfectly or not?

or it will still work but with limitations.

the same question with output pins. what is the condition of the output if one of the output pins is open?

Thank you and best regards,

Billy

Hi Sir,

The double input pin and output pins are used for sustaining high current.

With one open, have high risk to break the part as with high current.
