MIC4424BWM General Description

The MIC4423/4424/4425 family are highly reliableBiCMOS/DMOS buffer/driver/MOSFET drivers. TheyarehigheroutputcurrentversionsoftheMIC4426/4427/4428, which are improved versions ofthe MIC426/427/428. All three families are pincompatible. The MIC4423/4424/4425 drivers arecapable of giving reliable service in more demandingelectrical environments than their predecessors. Theywill not latch under any conditions within their powerand voltage ratings. They can survive up to 5V of noisespiking, of either polarity, on the ground pin. They canaccept, without either damage or logic upset, up to halfan amp of reverse current (either polarity) forced backinto their outputs.The MIC4423/4424/4425 series drivers are easier touse, more flexible in operation, and more forgiving thanother CMOS or bipolar drivers currently available. TheirBiCMOS/DMOS construction dissipates minimumpower and provides rail-to-rail voltage swings.Primarily intended for driving power MOSFETs, theMIC4423/4424/4425 drivers are suitable for drivingother loads (capacitive, resistive, or inductive) whichrequire low-impedance, high peak currents, and fastswitching times. Heavily loaded clock lines, coaxialcables, or piezoelectric transducers are someexamples. The only known limitation on loading is thattotal power dissipated in the driver must be kept withinthe maximum power dissipation limits of the package.See MIC4123/4124/4125 for high power and narrowpulse applications.
