MIC4417YM4-TR [Microchip]

The MIC4416 and MIC4417 IttyBitty® low-side MOSFET gate 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 gate 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 4.5 V to 18 V 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 10 V, are appropriate for use with standard N-Channel MOSFETs. Low supply voltages, such as 5 V, are appropriate for use with logic-level N-Channel MOSFETs. In a low-side configuration, the gate 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.
