MIC4467/4468/4469

Quad 1.2A-Peak Low-Side MOSFET Driver

Bipolar/CMOS/DMOS

General Description

Features

•

Built using reliable, low power CMOS processes

Latchproof. Withstands 500mA Inductive Kickback

3 Input Logic Choices

Symmetrical Rise and Fall Times............................25ns

Short, Equal Delay Times .......................................75ns

High Peak Output Current....................................... 1.2A

Wide Operating Range ..................................4.5 to 18V

Low Equivalent Input Capacitance (typ) .................. 6pF

Inputs = Logic 1 for Any Input From 2.4V to V_S

ESD Protected

TheMIC4467/8/9familyof4-outputCMOSbuffer/driversisan

expansion from the earlier single- and dual-output drivers, to

whichtheyarefunctionallycloselyrelated. Becausepackage

pin count permitted it, each driver has been equipped with a

2-inputlogicgateforaddedﬂexibility.Placingfourhigh-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 single-

input 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

drivercapableofhighpeakcurrents,rail-to-railvoltageswings,

and fast switching times. For example, heavily loaded clock

lines, coaxialcables, andpiezoelectrictransducerscanallbe

driven easily with MIC446X series drivers. The only limitation
