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.
The MIC5012 is ESD sensitive.
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.
Test conditions reflect worst case high-side driver performance. Low-side and bootstrapped topologies are significantly faster—see
Applications Information. Maximum value of switching speed seen at 125°C, units operated at room temperature will reflect the typical
values shown.
