Product details

Half-bridge gate driver for motor drives and power supplies

The IR2181SPBF is a half-bridge gate driver with two independent, non-inverting channels. It drives IGBTs and N-Channel MOSFETs, with a 600 V bootstrap rating and 1.9 A source, 2.3 A sink peak output.

8-SOIC package — rework and layout notes

The IR2181SPBF comes in an 8-SOIC package with 3.90 mm width. The -40°C to 150°C junction temperature range gives margin for motor-drive environments.

Active lifecycle — no LTB clock ticking

The IR2181SPBF carries an Active lifecycle status and is ROHS3 compliant. For BOM planning, this part is still a standard production choice suitable for new designs and volume builds.

Frequently asked questions

Can IR2181SPBF drive both high-side and low-side MOSFETs in a half-bridge?

Yes, the IR2181SPBF is configured as a half-bridge driver with two independent, non-inverting channels. It drives both the high-side and low-side switches, with the high-side channel powered by a bootstrap supply rated to 600 V.

Can IR2181SPBF drive both IGBT and MOSFET?

Yes, the gate type is specified for both IGBT and N-Channel MOSFET. The 1.9 A source and 2.3 A sink peak output is sufficient to drive medium-power devices in both families.
