The Texas Instruments UCC27423MDREP is a dual-channel, low-side gate driver for N-channel and P-channel MOSFETs. Each channel delivers 4A peak source and 4A peak sink current, with 20 ns rise and 15 ns fall times typical.
The 4A peak source and sink current determines how fast the MOSFET gate voltage slews. The 15 ns fall time (typical) keeps the Miller plateau short.
Military temperature range — deployment context
The driver is characterized over the entire span.
The ROHS3 compliance means it meets the latest EU restriction on hazardous substances, which avoids a paperwork snag for export builds.
