TPS25925: Response time for current limit function

Part Number: TPS25925

Is there response time spec for start current limit function on TPS259251?

Datasheet P6 is described t_FastOffDly at 300ns (and t_OFFdly: 0.4μs), but I look like P11: Figure 30 is more fast response (ns order) than P6.

I want to confirm correct response spec.

Or is OCP response time depend on condition?

※Under reviewing current limit is 3.7A (R_ILIM: 100kΩ)

Best regards,

Hi Satoshi,

The value of the Fast-trip comparator delay in the table is a typical value. So it is possible that you can see the actual value a less than or greater than the typical value. The typical value is provided to give an idea on how fast the device reacts to a short and turns Off the FET.
