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 flexibility. 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-efficiency, 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.
