MICROCHIPMIC4427ZMMIC4427ZM MOSFET Gate Driver, 1.5 A, 18V 8-Pin, SOIC

The Microchip highly reliable dual low-side MOSFET drivers is fabricated on a BiCMOS/DMOS process is for low power consumption and high efficiency. These drivers translate TTL or CMOS input logic levels to output voltage levels that swing within 25 mV of the positive supply or ground. Comparable bipolar devices are capable of swinging only to within 1 V of the supply. It is available in three configurations dual inverting, dual non-inverting, and one inverting plus one non-inverting output. Primarily intended for driving power MOSFETs, MIC4427 series drivers are suitable for driving other loads capacitive, resistive, or inductive that require low-impedance, high peak current, and fast switching time. Other applications include driving heavily loaded clock lines, coaxial cables, or piezoelectric transducers. The only load limitation is that total driver power dissipation must not exceed the limits of the package.
