MIC4467/4468/4469 Quad 1.2A Low-Side MOSFET Driver Bipolar/CMOS/DMOS General Description 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 pack- age 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 applica- tions, one of these drivers can replace not only two packages of single-input drivers, but some of the associated logic as well. Features Built using reliable, low power CMOS processes Latchproof.

The only limitation on loading is that total power dissipation in the IC must be kept within the power dissipation limits of the package. The MIC446xX series drivers are built using a BCD process. They will not latch under any conditions within their power and voltage ratings. They are not subject to damage when up to 5V of noise spiking (either polarity) occurs on the ground line. They can accept up to half an amp of inductive kickback current (either polarity) into their outputs without damage or logic upset. Ordering Information Truth Table Part No. Package Temp.
