5 MIC4426/4427/4428 Dual High Speed MOSFET Driver Bipolar/CMOS/DMOS Process General! Description The MIC4426/4427/4428 family of buffer/drivers are built using a new, highly reliable BICMOS/DMOS process. They are improved versions of the MIC426/427/428 family of buffer/ drivers (with which they are pin compatible) and are capable of giving reliable service in far more demanding electrical environments: they will not latch under any conditions within their power and voltage ratings. They are not subject to damage when up to 5V of noise spiking, of either polarity, occurs on the ground pin. They can accept, without either damage or logic upset, up to half an amp of reverse current (of either polarity) being forced back into their outputs. All terminals are fully protected against up to 2kV of electrostatic discharge. Asa result, the MIC4426/27/28 series drivers are much easier to use, more flexible in operation, and much more forgiving than any other driver, CMOS or bipolar, currently available. Because they are fabricated in BICMOS/DMOS, they dissipate a minimum of power, and provide rail-to-rail voltage swings to better insure the logic state of any load they are driving. Although primarily intended for driving power MOSFETs, the 4426/4427/4428 series drivers are equally well suited to driving any other load (capacitive, resistive, or inductive) which requires a low-impedance driver capable of high peak currents and fast switching times. For example, heavily loaded clock lines, coaxial cables, or piezoelectric transducers allcan be driven from the MIC 4426/27/28. The only known limitation on loading is that total power dissipated in the driver must be kept within the maximum power dissipation limits of the package.
