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 MIC5014/5015 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 operating temperature 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
Applications Information. Maximum value of switching time seen at 125°C, unit operated at room temperature will reflect the typical value
shown.
Note 5: “Asserted” refers to a logic high on the MIC5014 and a logic low on the MIC5015.
