Other Parts Discussed in Thread: TPS25200, TPS2660
Hi,
I am considering the TPS25921A current limit.
This device can limit current with ILIMIT and IFASTRIP.
I now set the following conditions, I want to limit the current at 0.3A.
In my circuit, a peak current of about 0.35 A flows. However, since the current rapidly increases, current detection does not work. Since the peak current is 0.35 A, it can not be limited by IFASTRIP.
In the data sheet, it is stated that the current limit amplifier can not respond quickly because the bandwidth is limited.
Please tell me how fast the response speed is.
(conditions)
Ilimit = 0.3 A (R (ILIM) = 29 kΩ)
I (FASTTRIP) = 0.77 A
Best Regards,
