The MIC4426/4427/4428 family are highly-reliable dual low-side MOSFET drivers fabricated on a BiCMOS/DMOS process for low power consumption and high efficiency. These drivers translate TTL or CMOS input logic levels to output voltage levels that swing within 25mV of the positive supply or ground. Comparable bipolar devices are capable of swinging only to within 1V of the supply. The MIC4426/7/8 is available in three configurations: dual inverting, dual noninverting, and one inverting plus one noninverting output. Bipolar/CMOS/DMOS construction
Latch-up protection to >500mA reverse current
1.5A peak output current
4.5V to 18V operating range
Low quiescent supply current
4mA at logic 1 input
