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 T_A = 25°C and T_A = 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.
