The MIC4426/4427/4428 family are highly-reliable dual low-side MOSFET drivers fabricated on a BiCMOS/DMOS pro-cess for low power consumption and high efficiency. Thesedrivers translate TTL or CMOS input logic levels to outputvoltage levels that swing within 25mV of the positive supplyor ground. Comparable bipolar devices are capable of swing-ing only to within 1V of the supply. The MIC4426/7/8 isavailable in three configurations: dual inverting, dual nonin-verting, and one inverting plus one noninverting output.The MIC4426/4427/4428 are pin-compatible replacementsfor the MIC426/427/428 and MIC1426/1427/1428 with im-proved electrical performance and rugged design (Refer tothe Device Replacement lists on the following page). Theycan withstand up to 500mA of reverse current (either polarity)without latching and up to 5V noise spikes (either polarity) onground pins.Primarily intended for driving power MOSFETs, MIC4426/7/8drivers are suitable for driving other loads (capacitive, resis-tive, or inductive) which require low-impedance, high peakcurrent, and fast switching time. Other applications includedriving heavily loaded clock lines, coaxial cables, or piezo-electric transducers. The only load limitation is that total driverpower dissipation must not exceed the limits of the package.
