MIC4451/4452  
12A-Peak Low-Side MOSFET Driver  
Bipolar/CMOS/DMOS Process  
General Description  
Features  
MIC4451 and MIC4452 CMOS MOSFET drivers are  
tough, efficient, and easy to use. The MIC4451 is an  
inverting driver, while the MIC4452 is a non-inverting  
driver.  
• BiCMOS/DMOS Construction  
• Latch-Up Proof: Fully Isolated Process is Inherently  
Immune to Any Latch-up.  
• Input Will Withstand Negative Swing of Up to 5V  
• Matched Rise and Fall Times: 25ns  
•..High Peak Output Current: 12A Peak  
•..Wide Operating Range: 4.5V to 18V  
•..High Capacitive Load Drive: 62,000Pf  
•..Low Delay Time: 30ns (typ)  
•..Logic High Input for Any Voltage from 2.4V to VS  
•..Low Supply Current450µA With Logic 1 Input  
•..Low Output Impedance: 1.0Ω  
Both versions are capable of 12A (peak) output and can  
drive the largest MOSFETs with an improved safe  
operating margin. The MIC4451/4452 accepts any logic  
input from 2.4V to VS without external speed-up capacitors  
or resistor networks. 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.  
MIC4451/4452 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 VS  
• Low Equivalent Input Capacitance (typ): 7pF  
Modern Bipolar/CMOS/DMOS construction guarantees  
freedom from latch-up. The rail-to-rail swing capability of  
CMOS/DMOS insures adequate gate voltage to the  
MOSFET during 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.
