Device Overview

Summary

The MIC4414 and MIC4415 are low-side MOSFET drivers designed to switch an N-channel enhancement type MOSFET in low-side switch applications. The MIC4414 is a non-inverting driver and the MIC4415 is an inverting driver. These drivers feature short delays and high peak current to produce precise edges and rapid rise and fall times. The MIC4414/15 are powered from a 4.5V to 18V supply and can sink and source peak currents up to 1.5A, switching a 1000pF capacitor in 12ns. The on-state gate drive output voltage is approximately equal to the supply voltage (no internal regulators or clamps). High supply voltages, such as 10V, are appropriate for use with standard N-channel MOSFETs. Low supply voltages, such as 5V, are appropriate for use with many logic-level N-channel MOSFETs. In a low-side configuration, the driver can control a MOSFET that switches any voltage up to the rating of the MOSFET. The MIC4414 and MIC4415 are available in an ultra-small 4-pin 1.2mm x 1.2mm thin QFN package and is rated for –40°C to +125°C junction temperature range.
