The 2A peak source/sink charges and discharges MOSFET gate capacitance. With 10ns edges, this driver switches a moderate-size FET in tens of nanoseconds. Inverting and non-inverting inputs match PWM controller logic polarity without an inverter gate.
It will handle under-hood engine bay temperatures, outdoor telecom enclosures, and factory-floor motor drives without derating drama.
Yes, each of the two independent driver channels provides both inverting and non-inverting inputs, giving flexibility to match the PWM controller's logic polarity.
The ADP3631ARZ-R7 is the closest functional alternative — same dual low-side driver with 2A peak, 10ns edges, and inverting/non-inverting inputs, but in a different package variant. Verify the package footprint compatibility for your board before substituting.
