Note 1

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Electrical speciﬁcations do not apply when

operating the device beyond its speciﬁed

Operating Ratings.

Note 2

The MIC5011 is ESD sensitive.

Note 3

Minimum and maximum

Electrical Characteristics are 100% tested at TA = 25°C and TA = 85°C, and 100% guaranteed over the entire

range. Typicals are characterized at 25°C and represent the most likely parametric norm.

Note 4

Test conditions reﬂect worst case high-side driver performance. Low-side and bootstrapped topologies are signiﬁcantly faster—see

Appli-

cations Information. Maximum value of switching speed seen at 125°C, units operated at room temperature will reﬂect the typical values

shown.
