Dual 1.5A MOSFET driver — what it does and where it fits
The Maxim Integrated MAX4428CPA is a dual-channel, non-inverting MOSFET driver rated for 1.5 A peak output per channel. It is designed to drive the gate capacitance of power MOSFETs and IGBTs in switch-mode power supplies, motor drives, and DC-DC converters where two independent low-side gates need fast, matched drive. The dual-channel layout saves board space compared to two single drivers, and the non-inverting logic means the output follows the input without a polarity inversion — useful when the PWM controller already sets the correct phase.
RoHS non-compliant — what it means for your BOM
The MAX4428CPA is marked RoHS non-compliant, which typically indicates the part uses lead (Pb) in the solder finish or internal construction. This is common for legacy industrial and military-grade parts that were designed before the RoHS directive. If your production line runs lead-free reflow, you will need a waiver or an exemption for this component. For maintenance and repair of older equipment, the non-compliant status is usually not a blocker — the original BOM likely specified lead-bearing solder anyway.
