... General Description The MIC4223/MIC4224/MIC4225 are a family of a dual 4A, High-Speed, Low-side MOSFET drivers with logic-level driver enables. The devices are fabricated on Micrel’s Bipolar/CMOS/DMOS (BCD) process and operate from a 4.5V to 18V supply voltage. The devices parallel Bipolar and CMOS output stage architecture provides high-current ...

... The drivers come in both inverting and non-inverting versions. Each driver has an enable pin that turns the output off (low) regardless of the input. The MIC4223 is a dual inverting driver. The MIC4224 is a dual non-inverting driver and the MIC4225 contains an inverting and non-inverting driver. Enable Each output has an independent enable pin that forces the output low when the enable pin is driven low ...
