High-side/low-side driver with 500 V bootstrap — what the ratings mean for the switching stage
The STMicroelectronics L6498DTR is a high-side or low-side gate driver for IGBTs and N-channel MOSFETs. Peak output is 2 A source and 2.5 A sink. The 500 V maximum bootstrap voltage sets the high-side rail ceiling. Matched 25 ns rise and fall times simplify dead-time programming. Supply range is 10 V to 20 V. Input thresholds are CMOS/TTL-compatible with VIL of 1.45 V and VIH of 2 V.
Temperature grade and package — industrial and automotive environments
Rated for junction temperatures from -40°C to 125°C, the L6498DTR handles the thermal extremes found in motor-drive cabinets, outdoor telecom rectifiers, and under-hood automotive inverter modules. The 8-SOIC package with a 3.90 mm body width fits standard SOIC-8 land patterns and keeps the board footprint small. Surface-mount assembly is the norm for reflow-soldered power stages. The two driver channels are independent, so the part can also be used as a dual low-side driver if the bootstrap diode is not needed.
Sourcing and lifecycle — active, ROHS3, no LTB risk
The part is listed as Active with ROHS3 compliance. No end-of-life notice or last-time-buy window is tracked. It is available through independent distribution channels and can be quoted to order against an RFQ.
