Quad 1.2A-Peak Low-Side MOSFET Driver
Bipolar/CMOS/DMOS General Description Features The MIC4467/8/9 family of 4-output CMOS buffer/drivers is an
expansion from the earlier single-and dual-output drivers, to
which they are functionally closely related. Because package
pin count permitted it, each driver has been equipped with a
2-input logic gate for added flexibility. Placing four high-power
drivers in a single package also improves system reliability
and reduces total system cost. In some applications, one of
these drivers can replace not only two packages of singleinput drivers, but some of the associated logic as well. Although primarily intended for driving power MOSFETs,
and similar highly capacitive loads, these drivers are equally
well suited to driving any other load (capacitive, resistive, or
inductive), which requires a high-efficiency, low-impedance
driver capable of high peak currents, rail-to-rail voltage swings,
and fast switching times. For example, heavily loaded clock
lines, coaxial cables, and piezoelectric transducers can all be
driven easily with MIC446X series drivers. The only limitation Built using reliable, low power CMOS processes
