Tool/software:
I have a question regarding the Recommended Operating Conditions for the WDI input on the TPS3110.
In the datasheet, it mentions that the WDI input transition rate should be 100ns/V max “at MR’”:
Could you please clarify what “at MR’” refers to in this context?
Does it mean that the 100ns/V max applies when MR' is held low?
Additionally, the datasheet recommends a 100nF capacitor on the MR pin:
Based on this, I calculated the required current to meet the 100ns/V condition:
i = (dV/dt) × C = (1V / 100ns) × 100nF = 1A
Assuming this calculation is correct, it implies I would need a 1A driver connected to the MR pin — which seems quite unreasonable.
Could you please advise?
