MIC4426/4427/4428  
Dual 1.5A-Peak Low-Side MOSFET Driver  
General Description  
Features  
The MIC4426/4427/4428 family are highly-reliable dual low-  
sideMOSFETdriversfabricatedonaBiCMOS/DMOSprocess  
for low power consumption and high efficiency.These drivers  
translate TTL or CMOS input logic levels to output voltage  
levelsthatswingwithin25mVofthepositivesupplyorground.  
Comparable bipolar devices are capable of swinging only  
to within 1V of the supply. The MIC4426/7/8 is available in  
three configurations: dual inverting, dual noninverting, and  
one inverting plus one noninverting output.  
• Bipolar/CMOS/DMOS construction  
• Latch-up protection to >500mA reverse current  
• 1.5A-peak output current  
• 4.5V to 18V operating range  
• Low quiescent supply current  
4mA at logic 1 input  
400µA at logic 0 input  
• Switches 1000pF in 25ns  
• Matched rise and rall times  
• 7Ω output impedance  
• <40ns typical delay  
The MIC4426/4427/4428 are pin-compatible replacements  
for the MIC426/427/428 and MIC1426/1427/1428 with im-  
proved electrical performance and rugged design (Refer to  
the Device Replacement lists on the following page). They  
can withstand up to 500mAof reverse current (either polarity)  
without latching and up to 5V noise spikes (either polarity)  
on ground pins.  
• Logic-input threshold independent of supply voltage  
• Logic-input protection to –5V  
• 6pF typical equivalent input capacitance  
• 25mV max. output offset from supply or ground  
• Replaces MIC426/427/428 and MIC1426/1427/1428  
• Dual inverting, dual noninverting, and inverting/  
noninverting configurations

driversaresuitablefordrivingotherloads(capacitive,resistive,  
orinductive)whichrequirelow-impedance,highpeakcurrent,  
and fast switching time. Other applications include driving  
heavily loaded clock lines, coaxial cables, or piezoelectric  
transducers. The only load limitation is that total driver power  
dissipation must not exceed the limits of the package.  
• ESD protection  
Applications  
• MOSFET driver  
• Clock line driver  
• Coax cable driver  
Note See MIC4126/4127/4128 for high power and narrow  
pulse applications.  
• Piezoelectic transducer driver
