MIC4467/4468/4469
Quad 1.2A-Peak Low-Side MOSFET Driver Bipolar/CMOS/DMOS
General Description
MIC4467/8/9 family 4-output CMOS buffer/drivers expansion from earlier single- dual-output drivers, which they functionally closely related. Because package count permitted each driver been equipped with 2-input logic gate added flexibility. Placing four highpower drivers single package also improves system reliability reduces total system cost. some applications, these drivers replace only packages single-input drivers, some associated logic well. Although primarily intended driving power MOSFETs, similar highly capacitive loads, these drivers equally well suited driving other load (capacitive, resistive, inductive), which requires high-efficiency, low-impedance driver capable high peak currents, rail-to-rail voltage swings, fast switching times. example, heavily loaded clock lines, coaxial cables, piezoelectric transducers
