Injection current limit

ads22 on Oct 10, 2025

Category: Datasheet/Specs

Product Number: LTC6993-2, LTC699

Hi, I have a scenario where there can be an input signal on the TRIG pin while the LTC6993 is unpowered.
Is there a max. injection current limit for this pin? I cannot find in the datasheet.
Thanks!

Thanks Geneva.

Hi ads22,

The LTC6993 TRIG input is like a CMOS input. The current drawn by this pin is around microamperes, if not nanoamperes.

However, we don't recommend applying a voltage to any pin of the device if the device is not powered, as it will cause absolute maximum rating violations. This can cause harm to the device if applied for a long period of time.

Thanks,

Emrecan
