The MAX15024AATB+T is a single-channel low-side gate driver from Maxim Integrated, designed to drive N-channel MOSFETs in automotive and industrial power stages. The part drives a single low-side MOSFET with a peak output of 4A source and 8A sink, delivering fast 22ns rise and 16ns fall times into the gate load. Supply range from 4.5V to 28V covers 12V and 24V automotive rails with headroom for load-dump transients.
Drive strength and switching speed — what the ratings mean
The 8A sink capability is the standout figure here: it pulls gate charge down fast, which directly reduces turn-off switching losses in hard-switched topologies like boost converters, flyback supplies, and solenoid drivers. The 4A source is adequate for turn-on, but if you are driving a large-capacitance MOSFET (e.g., several nF of gate charge), check the gate drive loop inductance — the 22ns rise time can cause ringing if the layout is not tight. The asymmetric drive (weaker source, stronger sink) is intentional: it slows the turn-on edge slightly to control inrush or di/dt, then yanks the gate off hard to minimise overlap loss.
The part comes in a 10-TDFN (3x3 mm) with exposed pad.
It is an automotive-grade part (AEC-Q100), so expect the usual automotive supply chain — qualified through independent distribution.
