MIC4225数据手册集成电路（IC）的栅极驱动器规格书PDF

描述 Description

The MIC4223/MIC4224/MIC4225 are a family of a dual 4 A, high-speed, low-side MOSFET gate drivers with logic-level driver enables. The devices are fabricated on Bipolar/CMOS/DMOS (BCD) process and operate from a 4.5 V to 18 V 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 4 A of peak current from a 12 V supply and quickly charge and discharge a 2,000 pF load capacitance in under 15 ns, while allowing the outputs to swing within 0.3 V of VDD and 0.16 V of ground. The MIC4223/MIC4224/MIC4225 gate drivers 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 100 kΩ, 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 -5 V of voltage swing at -40 mA. Driver outputs are also protected to withstand 500 mA 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 complimentary (MIC4225). They are available in 8-pin SOIC and thermally enhanced ePadD 8-pin MSOP and support operating junction temperatures from -40°C to +125°C.
