Half-bridge MOSFET driver — what it is and where it fits
The RAJ20660AGNP#HA0 is a half-bridge based MOSFET driver from Renesas, designed to drive the high-side and low-side MOSFETs in a half-bridge topology. This class of driver is used in DC-DC converters, motor drive half-bridges, synchronous rectifier stages, and class-D audio output stages where one leg of the bridge switches the load between the supply rail and ground. The part is rated ROHS3 compliant, which keeps it clear of the restricted substances list for EU-market equipment and most global RoHS regimes.
Active lifecycle — no obsolescence risk for new designs
For a BOM line, this removes the urgency to stockpile or qualify a drop-in replacement.
What the half-bridge driver rating means for the BOM
A half-bridge MOSFET driver integrates the gate-drive timing and level-shifting for both the high-side and low-side FETs. The buyer's decision is whether the driver's output current, propagation delay, and bootstrap supply match the MOSFETs' gate charge and switching frequency in the target converter.
