Dual 2A low-side driver for synchronous MOSFET switching
It drives both N-Channel and P-Channel MOSFETs with a peak output current of 2A source and 2A sink per channel, making it suited for synchronous buck converters, push-pull topologies, and other low-side switching stages where two independent gates need fast, matched drive. Supply voltage range of 4V to 14V covers common 5V and 12V rails used in industrial and automotive power supplies. The inverting input type means the output goes high when the input is low — check your controller's polarity before laying out the PCB. Rise and fall times are 14ns and 15ns typical. Peak output is 2A source and 2A sink.
The 8-SOIC package keeps board area small, but verify the thermal impedance for your load — continuous 2A switching into a high-capacitance gate at 125°C may need airflow or a heatsink pad.
Logic interface and BOM fit
Logic thresholds are 1V VIL and 4V VIH. Minimum supply is 4V.
