MIC4223/MIC4224/MIC4225 Dual 4A, 4.5V to 18V, 15ns Switch Time, Low-Side MOSFET Drivers with Enable General Description Features 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 2000pF 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 -40mA. Driver outputs are also protected to withstand 500mA 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 e-PAD 8-pin MSOP and support operating junction temperatures from -40°C to +125°C. • 4.5V to 18V supply voltage operating range • High peak source/sink current – ±3A at VDD = 8V – ±4A at VDD = 12V • 15ns/15ns Rise and Fall times with 2000pF load • 25ns/35ns (Rising/Falling) input propagation delay • 20ns/45ns (Rising/Falling) enable propagation delay • Active-high driver enable inputs with 100kΩ pull-ups • CMOS and TTL logic input and enable thresholds independent of supply voltage • Driver input protection to -5V at -40mA • Output Latch-up protection to >500mA reverse current • Industry standard pin out with two package options – ePAD MSOP-8 (θJA = 60°C/W) – 8-pin SOIC (θJA = 120°C/W) • Available in dual-inverting (MIC4223), dual noninverting (MIC4224) and complementary (MIC4225) • Dual output drive by paralleling channels • -40°C to +125°C operating junction temperature range Block Diagram Applications • • • • • • • • High-Efficiency MOSFET switching Switch mode power supplies DC-to-DC converters Motor and solenoid drivers Clock and line drivers Synchronous rectifiers Pulse transformer drive Class D switching amplifiers Micrel Inc. • 2180 Fortune Drive • San Jose, CA 95131 • USA • tel +1 (408) 944-0800 • fax + 1 (408) 474-1000 • http://www.micrel.com June 2009 M9999-061109-A (408) 944-0800 PDF
