Overview

MIC4414/4415 1.
5A, 4.
5V to 18V, Low-Side MOSFET Driver General Description 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 Nchannel 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.
