MIC4224
MIC4224 is Low-Side MOSFET Drivers manufactured by Micrel Semiconductor.
- Part of the MIC4223 comparator family.
- Part of the MIC4223 comparator family.
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 throughout the MOSFETs Miller Region allowing the driver to sink and source 4A of peak current from a 12V supply and quickly charge and discharge a 2000p F load capacitance in under 15ns, while allowing the outputs to swing within 0.3V of VDD and 0.16V of ground. The MIC4223/MIC4224/MIC4225 driver and enable inputs feature
TTL and CMOS logic-level thresholds which are independent of supply voltage. Each driver features a dedicated active-high enable input which is internally pulled high to VDD through 100kΩ, allowing the pins to be left unconnected if it is not required to disable the driver outputs. The driver inputs have been designed to protect against ground bounce and are protected to withstand -5V of voltage swing at -40m A. Driver outputs are also protected to withstand 500m A of reverse current. The MIC4223/MIC4224/MIC4225 are available in three configurations using industry standard pin out; dual inverting (MIC4223), dual non-inverting (MIC4224) and plimentary (MIC4225). They are available in 8-pin SOIC and thermally enhanced e-PAD 8-pin MSOP and support operating junction temperatures from -40°C to +125°C.
