Overview

MIC426/427/428 Micrel MIC426/427/428 Dual 1.
5A-Peak Low-Side MOSFET Driver Bipolar/CMOS/DMOS Process General Description The MIC426/427/428 are dual high speed drivers.
A TTL/ CMOS input voltage level is translated into an output voltage level swing equal to the supply.
The DMOS output will be within 25mV of ground or positive supply.
Bipolar designs are capable of swinging only within 1 volt of the supply.
The low impedance high current driver outputs will swing a 1000pF load 18V in 30ns.
The unique current and voltage drive qualities make the MIC426/427/428 ideal power MOSFET drivers, line drivers, and dc-to-dc converter building blocks.
Input logic signals may equal the power supply voltage.
Input current is a low 1µA making direct interface to CMOS/bipolar switch-mode power supply control integrated circuits possible as well as open-collector analog comparators.
