MIC4426/7/8  
Dual 1.5A-Peak Low-Side MOSFET Drivers  
Features  
General Description  
• Bipolar/CMOS/DMOS Construction  
• Latch-Up Protected to >500 mA Reverse Current  
• 1.5A-Peak Output Current  
• 4.5V to 18V Operating Range  
• Low Quiescent Supply Current  
- 4 mA at Logic 1 Input  
The MIC4426/4427/4428 family are highly reliable dual  
low-side MOSFET drivers fabricated on  
a
BiCMOS/DMOS process for low power consumption  
and high efficiency. These drivers translate TTL or  
CMOS input logic levels to output voltage levels that  
swing within 25 mV of the positive supply or ground.  
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  
non-inverting, and one inverting plus one non-inverting  
output.  
- 400 μA at Logic 0 Input  
• Switches 1000 pF in 25 ns  
• Matched Rise and Fall Times  
• 7Ω Output Impedance

performance and rugged design. They can withstand  
up to 500 mA of reverse current (either polarity) without  
latching and up to 5V noise spikes (either polarity) on  
ground pins.  
• Logic-Input Protection to –5V  
• 6 pF Typical Equivalent Input Capacitance  
• 25 mV Max. Output Offset from Supply or Ground  
• Replaces MIC426/7/8 and MIC1426/7/8  
Primarily intended for driving power MOSFETs,  
MIC4426/7/8 drivers are suitable for driving other loads  
(capacitive, resistive, or inductive) that require  
low-impedance, high peak current, 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.  
• Dual inverting, dual non-inverting, and inverting/  
non-inverting configurations  
• ESD Protection  
Applications  
• MOSFET Driver  
• Clock Line Driver  
See MIC4126/4127/4128 for high power and narrow  
pulse applications.  
• Coax Cable Driver  
• Piezoelectric Transducer Driver
