Product details

The STMicroelectronics L6498D is a dual-channel gate driver that can be configured as either high-side or low-side for driving IGBTs and N-channel MOSFETs. The bootstrap supply supports a high-side voltage up to 500 V, making it suited for half-bridge and full-bridge topologies in motor drives, inverters, and switched-mode power supplies.

Supply voltage and bootstrap design

The device operates from a 10 V to 20 V supply rail, which covers the typical gate-drive voltages for IGBTs (15 V) and logic-level MOSFETs (10 V to 12 V). The 500 V maximum bootstrap voltage on the high side means the driver can float the gate drive up to a 500 V DC bus — common in 3-phase motor drives running off rectified 230 VAC or 400 VDC links. When sizing the bootstrap capacitor, factor in the 2.5 A sink current and switching frequency; the datasheet application section provides the calculation, but a 1 µF to 10 µF ceramic across the bootstrap diode is a typical starting point.

Frequently asked questions

Can the L6498D be used as a low-side driver?

Yes. Each of the two independent channels can be configured as either high-side or low-side, so you can use one channel as a low-side driver and the other as a high-side driver, or both as low-side drivers for two separate switches.

Is the L6498D compatible with IGBTs?

Yes, the L6498D is specified for driving both IGBTs and N-channel MOSFETs, with a gate type listed as IGBT and N-Channel MOSFET.

What is the closest pin-compatible alternative to the L6498D?

Within the same ST family, the L6498 is the base part number; the L6498D is the 8-SOIC variant. For a pin-compatible alternative with similar drive strength, consider the L6498 in the same package — confirm the exact logic thresholds and bootstrap rating against your design requirements.
