MICROCHIP MIC4416YM4-TR

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 non-inverting 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 minimal space. The MIC4416/7 are powered from a +4.5V to +18 supply voltage. The on-state 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 drive can control a MOSFET that switches any voltage up to the rating of the MOSFET. The MIC4416/7 are available in the SOT-143 package and are rated for the -40°C to +85°C ambient temperature range.
