MIC4126/27/28  
Dual 1.5A-Peak Low-Side MOSFET  
Drivers in Advanced Packaging  
General Description  
Features  
The MIC4126, MIC4127, and MIC4128 family are highly-  
reliable dual 1.5A low-side MOSFET drivers fabricated on  
Micrel’s BiCMOS/DMOS process. The devices feature low  
Dual 1.5A-peak drivers  
4.5V to 20V operating range  
Exposed backside pad packaging reduces heat  
ePAD SOIC-8L (θJA = 58°C/W)  
power  
consumption  
and  
high  
efficiency.  
The  
MIC4126/27/28 translate TTL or CMOS input logic levels to  
output voltage levels that swing within 25mV of the positive  
supply or ground whereas comparable bipolar devices are  
capable of swinging only to within 1V of the supply. The  
MIC4126/7/8 is available in three configurations: dual  
inverting, dual non-inverting, and complimentary output.  
ePAD MSOP-8L (θJA = 60°C/W)  
3mm x 3mm MLF™-8L (θJA = 60°C/W)  
Bipolar/CMOS/DMOS construction  
25mV maximum output offset from supply or ground  
Latch-up protection to >200mA reverse current  
Switches 1000pF in 25ns  
Logic-input threshold independent of supply voltage  
Logic-input protection to –5V  
6pF typical equivalent input capacitance  
The MIC4126/27/28 offer pin-compatible as well as smaller  
footprint replacements for the MIC4426/27/28 with  
improved packaging and electrical performance. The  
MIC4126/27/28 are available in exposed pad, EPAD,  
SOIC-8L and MSOP-8L options as well as a small-size  
3mm x 3mm MLF™-8L option. The devices have an input  
operating range of 4.5V to 20V.  
Dual inverting, dual non-inverting, and complementary  
configurations  
Primarily intended for driving power MOSFETs,  
MIC4426/7/8 drivers are suitable for driving other loads  
(capacitive, resistive, or inductive) which require low-  
impedance, high peak current, and fast switching time. The  
devices can withstand up to 500mA of reverse current  
(either polarity) without latching and up to 5V noise spikes  
(either polarity) on ground pins.  
-40°C to +125°C operating junction temperature range  
Applications  
DC/DC converters  
Motor drivers  
Clock line driver
