LMZ31506: About PWRGD terminal specifications of LMZ31506RUQR

Part Number: LMZ31506

Could you tell us about the PWRGD terminal specifications of the LMZ31506RUQR?

There is a description of the TYP value for the PWRGD threshold, but there is no description of the Max value and Min value.

Could you tell me about the value?

    Hello,

    The power good pin does not have a min or max spec for this device. The typical specification will provide the percentage thresholds at which power good will assert and de-assert. For example, when Vout rises and achieves 94% of the set point, PG will assert high. If VOUT rises to 109% of the VOUT set point, PG will de-assert. For VOUT falling (from above the set point), PG will assert high when the output voltage falls to 106% of the set point. As VOUT decreases further, PG will de-assert when VOUT falls below 91% of the set point. 

    Sincerely,

    Alec Biesterfeld
