MIC4416/4417 Micrel, Inc. MIC4416/4417
IttyBittyв„ў Low-Side MOSFET Driver General Description Features The MIC4416 and MIC4417 IttyBittyв„ў low-side MOSFET
drivers are designed to switch an N-channel enhancementtype MOSFET from a TTL-compatible control signal in lowside 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. +4.5V to +18V operation Low steady-state supply current
50ВµA typical, control input low
370ВµA typical, control input high 1.2A nominal peak output
3.5Ω typical output resistance at 18V supply
7.8Ω typical output resistance at 5V supply 25mV maximum output offset from supply or ground Operates in low-side switch circuits TTL-compatible input withstands –20V ESD protection Inverting and noninverting versions The MIC4416/7 is powered from a +4.5V to +18V supply
voltage. 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 logic-level
N-channel MOSFETs. Applications In a low-side configuration, the driver can control a MOSFET
that switches any voltage up to the rating of the MOSFET. Battery conservation
