MIC4416/4417
IttyBitty™ Low-Side MOSFET Driver
General Description
The MIC4416 and MIC4417 IttyBitty™ low-side MOSFET
drivers are designed to switch an N-channel enhancement-
type MOSFET from a TTL-compatible control signal in low-
side switch applications. The MIC4416 is noninverting and
the MIC4417 is inverting. These drivers feature short delays
and high peak current to produce precise edges and rapid
rise and fall times. Their tiny 4-lead SOT-143 package uses
minimum space.
The MIC4416/7 is powered from a +4.5V to +18V supply
voltage. The on-state gate drive output voltage is approxi-
mately 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 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 MIC4416 is available in the SOT-143 package and
is rated for –40°C to +85°C ambient temperature range.
