The MIC4424YM-TR from Microchip is a dual 3A low-side MOSFET driver with one inverting and one non-inverting channel in SOIC-8 for half-bridge and push-pull drive applications.
The MIC4424YM-TR is a dual 3A low-side MOSFET driver from Microchip in SOIC-8, with one inverting (A) and one non-inverting (B) channel. The driver converts low-current logic signals (TTL/CMOS compatible, VIH=2.4V, VIL=0.8V) into high-current gate drive signals (3A peak source/sink). The output stage uses bipolar totem-pole (NPN emitter-follower for sourcing, NPN common-emitter for sinking), providing low output impedance: 2.5 ohm sourcing and 1.5 ohm sinking. The peak drive current is limited only by the output impedance and supply voltage: at VDD=12V driving a MOSFET with Qg=50nC, the rise time is approximately Qg/Ipeak = 50nC/3A = 17ns. The inverting channel A is useful for half-bridge drivers where the high-side MOSFET requires an inverted signal. The non-inverting channel B drives the low-side MOSFET directly. The matched propagation delays (30ns typical for both channels) and 15ns delay matching between channels ensure accurate dead-time control in bridge configurations. The input hysteresis (100mV) prevents oscillation from slow input edges. The supply current is 4mA quiescent (both outputs LOW). The device can operate up to 18V VDD, suitable for IGBT gate drive (15V typical) and logic-level MOSFET drive. The -YM-TR suffix specifies SOIC-8, industrial temperature, tape-and-reel. Applications include: synchronous buck converter gate drive, half-bridge motor drivers, and Class-D audio amplifier output stages.
