They are higher output current versions of the MIC4126/4127/4128, which are improved versions of the MIC4426/4427/4428.
All three families are pin-compatible.
The MIC4123/4/5 drivers are capable of providing reliable service in more demanding electrical environments than their predecessors.
They will not latch under any conditions within their power and voltage ratings.
They can survive up to 5V of noise spiking, of either polarity, on the ground pin.
They can accept, without either damage or logic upset, up to half an amp of reverse current (either polarity) forced back into their outputs.
The MIC4123/4/5 series drivers are easier to use, more flexible in operation, and more forgiving than other CMOS or bipolar drivers currently available.
Their BiCMOS/DMOS construction dissipates minimum power and provides rail-to-rail voltage swings.
Primarily intended for driving power MOSFETs, the MIC4123/4/5 drivers are suitable for driving other loads (capacitive, resistive, or induc...
