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.
The -40°C to 150°C junction temperature range gives margin for motor-drive environments.
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.
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.
