MIC4414/4415
1.5A, 4.5V to 18V,
Low-Side MOSFET Driver General Description Features 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
–40В°C to +125В°C junction temperature range. …
