TPS62867: spec check

GARETH OU

Part Number: TPS62867

The VIN falling slew rate of TPS62867 is lower than Vulvo, and there are special suggestions. 　Like the red frame. -10mV/us, converted to 　-10000V/s, the slope is very steep.

(1) Here MIN, -10mV/us, 　 does it mean that the power is off with a slower slope than -10mV/us?

(2) What happens if it does not meet the specifications?

Hello user,

(1) When a fast VIN dip occurs greater than -10mV/us (VIN is on) going below the UVLO value you would be outside of recommended operating conditions.

(2) If this condition is met, TPS62867 startup sequence would be altered and may differ from startup sequence shown in Figure 9-19.

Let me know if you have any further questions.

Thanks a lot!

Regards,
Dorian
