MD18623 High-Frequency Gate Driver for Dual N-Channel MOSFETs

MD18623 Dual Low-Side Gate Driver – High-Frequency MOSFET Driver IC (SOP-8)

Drive two N-channel MOSFETs independently with the MD18623 dual gate driver. Each channel delivers 5 A peak source and sink current with rail-to-rail output swing, and the matched 11 ns propagation delay on both rise and fall edges keeps dead-time symmetrical — critical for the synchronous buck and half-bridge topologies found in crypto-miner power supplies and hashboard DC-DC stages.

Minimal Delay Variation for Tight Timing Control

In a mining PSU running at high switching frequency, even a few nanoseconds of driver asymmetry can increase cross-conduction losses and cause MOSFET overheating. The MD18623's matched 11 ns delays ensure the high-side and low-side FETs transition cleanly, maximising converter efficiency and reducing thermal stress on the switching stage. The SOP-8 package simplifies PCB layout with short gate traces to the power FETs.

Wide Application Range Beyond Mining

While the MD18623 is a common replacement part in Antminer, Whatsminer, and Avalon PSUs, it also serves telecom/datacom power supplies, 48–72 V battery systems, motor control circuits, and Class D audio amplifier output stages — anywhere dual low-side MOSFET driving with tight timing is required.
