Mitel MIC4426/4427/4428 Dual 1.5A-Peak Low-Side MOSFET Driver Bipolar/CMOS/DMOS Process General Description The MIC4426/4427/4428 family are highly reliable BiCMOS/ DMOS buffer/driver/MOSFET drivers. They are pin compatible improved versions of the MIC426/427/428 family of buffer/ drivers and are capable of giving reliable service in more demanding electrical environments. They will not latch under any conditions within their power and voitage 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. The MIC4426/4427/4428 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 MIC 4426/ 4427/4428 drivers are suitable for driving other loads (capacitive, resistive, or inductive) which require low- impedance, high peak currents, and fast switching times. Heavily loaded clock lines, coaxial cables, or piezoelectric transducers are some examples. 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.
