MIC4421/4422  
9A-Peak Low-Side MOSFET Driver  
Bipolar/CMOS/DMOS Process  
General Description  
Features  
• BiCMOS/DMOS Construction  
• Latch-Up Proof: Fully Isolated Process is Inherently  
Immune to Any Latch-up.  
MIC4421 and MIC4422 MOSFET drivers are rugged, effi-  
cient, and easy to use. The MIC4421 is an inverting driver,  
while the MIC4422 is a non-inverting driver.  
• Input Will Withstand Negative Swing of Up to 5V  
• Matched Rise and Fall Times............................... 25ns  
• High Peak Output Current .............................. 9A Peak  
• Wide Operating Range.............................. 4.5V to 18V  
• High Capacitive Load Drive...........................47,000pF  
• Low Delay Time ........................................... 30ns Typ.  
Both versions are capable of 9A (peak) output and can drive  
the largest MOSFETs with an improved safe operating mar-  
gin. The MIC4421/4422 accepts any logic input from 2.4V to  
V
without external speed-up capacitors or resistor net-  
S
works. Proprietary circuits allow the input to swing negative  
by as much as 5V without damaging the part. Additional  
circuits protect against damage from electrostatic discharge.  
• Logic High Input for Any Voltage from 2.4V to V  
S
• Low Equivalent Input Capacitance (typ).................7pF  
• Low Supply Current..............450µA With Logic 1 Input  
• Low Output Impedance ........................................ 1.5Ω  
MIC4421/4422 drivers can replace three or more discrete  
components, reducing PCB area requirements, simplifying  
product design, and reducing assembly cost.  
• Output Voltage Swing to Within 25mV of GND or V  
S
Modern Bipolar/CMOS/DMOS construction guarantees free-  
dom from latch-up. The rail-to-rail swing capability of CMOS/  
DMOS insures adequate gate voltage to the MOSFET dur-  
ing power up/down sequencing. Since these devices are  
fabricated on a self-aligned process, they have very low  
crossover current, run cool, use little power, and are easy to  
drive.  
Applications  
• Switch Mode Power Supplies  
• Motor Controls  
• Pulse Transformer Driver  
• Class-D Switching Amplifiers  
• Line Drivers  
• Driving MOSFET or IGBT Parallel Chip Modules  
• Local Power ON/OFF Switch  
• Pulse Generators
