MIC4467/4468/4469 Micrel, Inc. MIC4467/4468/4469 Quad 1.2A-Peak Low-Side MOSFET Driver Bipolar/CMOS/DMOS General Description Features Built using reliable, low power CMOS processes The MIC4467/8/9 family of 4-output CMOS buffer/drivers is an Latchproof. Withstands 500mA Inductive Kickback expansion from the earlier single- and dual-output drivers, to 3 Input Logic Choices which they are functionally closely related. Because package Symmetrical Rise and Fall Times ............................25ns pin count permitted it, each driver has been equipped with a Short, Equal Delay Times .......................................75ns 2-input logic gate for added exibility. Placing four high-power High Peak Output Current ....................................... 1.2A drivers in a single package also improves system reliability Wide Operating Range .................................. 4.5 to 18V and reduces total system cost. In some applications, one of Low Equivalent Input Capacitance (typ) .................. 6pF these drivers can replace not only two packages of single- Inputs = Logic 1 for Any Input From 2.4V to V input drivers, but some of the associated logic as well. S ESD Protected Although primarily intended for driving power MOSFETs, and similar highly capacitive loads, these drivers are equally Applications well suited to driving any other load (capacitive, resistive, or General-Purpose CMOS Logic Buffer inductive), which requires a high-efciency, low-impedance Driving All 4 MOSFETs in an H-Bridge driver capable of high peak currents, rail-to-rail voltage swings, Direct Small-Motor Driver and fast switching times. For example, heavily loaded clock Relay or Peripheral Drivers lines, coaxial cables, and piezoelectric transducers can all be Dual Differential Output Power Drivers driven easily with MIC446X series drivers.
