july 2005 1 mic4467/4468/4469 mic4467/4468/4469 micrel, inc. general description the mic4467/8/9 family of 4-output cmos buffer/driv ers 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 ?exibility. 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 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-ef?ciency, 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 mic4467/4468/4469 quad 1.2a-peak low-side mosfet driver bipolar/cmos/dmos 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 applications ? general-purpose cmos logic buffer ? driving all 4 mosfets in an h-bridge ? direct small-motor driver ? relay or peripheral drivers ? dual differential output power drivers ? ccd driver ? pin-switching network driver logic diagrams 1a v s 1b2a 2b 3a 3b 4a 4b 1y2y 3y 4y gnd 12 3 4 5 6 8 9 1312 11 10 14 7 mic4468 1a v s 1b2a 2b 3a 3b 4a 4b 1y2y 3y 4y gnd 12 3 4 5 6 8 9 1312 11 10 14 7 mic4467 1a v s 1b2a 2b 3a 3b 4a 4b 1y2y 3y 4y gnd 12 3 4 5 6 8 9 1312 11 10 14 7 mic4469 micrel, inc. ? 2180 fortune drive ? san jose, ca 95131 ? usa ? tel + 1 (408) 944-0800 ? fax + 1 (408 ) 474-1000 ? http://www.micrel.com downloaded from: http:///
