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 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.
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.
In a low-side configuration, the driver can control a
MOSFET that switches any
voltage up to the rating of the
MOSFET.
