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 high-power drivers single package also improves system reliability reduces total system cost. some applications, these drivers replace only packages singleinput 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 driven easily with MIC446X series drivers. only limitation
