MIC4480

The MIC4478, MIC4479, and MIC4480 are low-side dual MOSFET drivers are designed to switch N-channel enhancement type MOSFETs from TTL-compatible control signals for low-side switch applications. The MIC4478 is dual non-inverting, the MIC4479 is dual inverting, and the MIC4480 is complimentary non-inverting and inverting. These drivers feature short delays and high peak currents to produce precise edges and rapid rise and fall times. The MIC4478/4479/4480 are powered from a +4.5V to +32V supply voltage. The on-state gate drive output voltage is approximately equal to the supply voltage (no internal regulators or clamps). In a low-side configuration, the drivers can control a MOSFET that switches any voltage up to the rating of the MOSFET. The MIC4478/4479/4480 are available in the 8-lead SOIC (ePAD and non-ePAD) package and are rated for the –40°C to +125°C ambient temperature range.
