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.

The MIC426 requires 1/5 the current of the pin compatible bipolar DS0026 device. This is important in dc-to-dc converter applications with power efficiency constraints and high frequency switch mode power supply applications. Quiescent current is typically 6mA when driving a 1000pF load 18V at 100kHz. Micrel The inverting MIC426 driver is pin compatible with the bipolar DS0026 and MMH0026 devices. The MIC427 is non-inverting; the MIC428 contains an inverting and non-inverting driver.
