MIC4128YME

The MIC4128 family is highlyreliable dual 1.5A low-side MOSFET drivers fabricated on Micrel’s BiCMOS/DMOS process. The devices feature low power consumption and high efficiency. The MIC4128 translate TTL or CMOS input logic levels to output voltage levels that swing within 25mV of the positive supply or ground whereas comparable bipolar devices are capable of swinging only to within 1V of the supply. The MIC4128 is available in three configurations: dual inverting, dual non-inverting, and complimentary output. The MIC4128 are available in exposed pad, EPAD, SOIC-8L and MSOP-8L options as well as a small-size 3mm x 3mm MLF™-8L option. The devices have an input operating range of 4.5V to 20V. The devices can withstand up to 500mA of reverse current (either polarity) without latching and up to 5V noise spikes (either polarity) on ground pins.
