The MIC4420YMMTR from Microchip is a 6A non-inverting low-side MOSFET driver with 20ns rise time in MSOP-8 for high-frequency switching power supply drive.
The MIC4420YMMTR is a 6A non-inverting low-side MOSFET driver from Microchip in MSOP-8 (with exposed pad), operating from 4.5-18V. The non-inverting logic means the output follows the input: INPUT HIGH = OUTPUT HIGH (driving the MOSFET gate HIGH = MOSFET on). The output stage uses bipolar totem-pole (NPN emitter-follower sourcing, NPN common-emitter sinking), providing low impedance in both directions. The 6A peak output current charges/discharges large MOSFET gate capacitances quickly: for a MOSFET with Qg=100nC, t_rise = 100nC/6A = 17ns. The output impedance is 1.5 ohm (sourcing) and 1.0 ohm (sinking) at VDD=15V. The propagation delay is 30ns typical with 5ns rise/fall times into 1000pF. The input hysteresis (200mV) prevents oscillation from slow input edges. The supply current is 1.5mA quiescent. The device matches the popular TC4420 pinout and specifications. The -YMMTR suffix specifies MSOP-8 with exposed pad, tape-and-reel. The exposed pad must be connected to GND for proper thermal performance. Applications include: power MOSFET gate drive in DC-DC converters, motor drive, and Class-D audio amplifiers.
