Part Number: TLV172

Hi team,

Do we have high output current Comparator (>=120mA), I see most devices have max ~70mA, like TLV172.

Thanks a lot.

Best regards,

Hi Yang,

The TLV172 is an op amp. This device, due to the back to back diodes, is not recommended to be used as a comparator. I recommend posting a question to the comparator forum.

Thank you,

I am not aware of any such comparator.

It is possible to add a buffer behind any suitable comparator. Devices like the BUF634A are intended for analog signals; for the digital output of a comparator, something like the UCC27517 would be simpler and more robust. What voltages do you need?

Hi Yang,

can you tell more about your application? Why do you need such a high output current?

Hello Yang,

Does the output need to sink high current source high current or both?

What is the output voltage range?
