About this product
IR2106S is a high- and low-side gate driver IC from Infineon (formerly International Rectifier) for half-bridge power stages using MOSFETs or IGBTs. It is used in motor controllers, inverters and switching power supply designs where the high-side device must be driven floating above ground.

Frequently asked questions
Why is a bootstrap circuit needed with this driver?
The high-side output floats with the switching node, so its gate supply is typically generated with a bootstrap diode and capacitor. Follow the bootstrap wiring in the datasheet to keep the high-side gate biased correctly.
Can it drive IGBTs as well as MOSFETs?
Yes, it is intended for driving both power MOSFETs and IGBTs in half-bridge configurations. Confirm the gate charge and drive requirements of your specific device against the datasheet.
