MIC4416/4417
IttyBitty™ Low-Side MOSFET Driver
General Description
Features
The MIC4416 and MIC4417 IttyBitty™ low-side MOSFET • +4.5V to +18V operation
drivers are designed to switch an N-channel enhancement- • Low steady-state supply current
type MOSFET from a TTL-compatible control signal in low-
50µA typical, control input low
side switch applications. The MIC4416 is noninverting and
370µA typical, control input high
the MIC4417 is inverting. These drivers feature short delays • 1.2A nominal peak output
and high peak current to produce precise edges and rapid
3.5Ω typical output resistance at 18V supply
rise and fall times. Their tiny 4-lead SOT-143 package uses
7.8Ω typical output resistance at 5V supply
minimum space.
• 25mV maximum output offset from supply or ground
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
• Operates in low-side switch circuits
• TTL-compatible input withstands –20V
• ESD protection
• Inverting and noninverting versions
for use with standard N-channel MOSFETs. Low supply _Applications
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.
• Battery conservation
• Solenoid and motion control
• Lamp control
• Switch-mode power supplies
The MIC4416 is available in the SOT-143 package and
is rated for –40°C to +85°C ambient temperature range.
