Gate Driver IR2110S
Gate Driver IR2112S
Previous
The IR2110S is a high-voltage, high-speed gate driver IC with independent high- and low-side referenced output channels. It supports floating operation up to +500V and is ideal for driving MOSFETs or IGBTs in half-bridge and full-bridge configurations. With 3.3V logic compatibility, undervoltage lockout, and matched propagation delays, it offers robust and reliable switching performance.
