The IR2111 High-Low Side Gate Driver for Power MOSFETs / IGBTs is a high-voltage, high-speed power driver IC designed to control both high-side and low-side N-channel MOSFETs or IGBTs. It provides independent gate drive outputs with built-in level shifting and protection, allowing efficient switching in half-bridge and full-bridge power configurations. The device supports up to 600V operation with fast propagation delay, making it ideal for high-performance applications such as motor control, DC-DC converters, UPS systems, and switching power supplies. Its compact design ensures reliable operation, reduced switching losses, and excellent noise immunity in demanding environments.
Features
- High and low side driver configuration for N-channel MOSFETs or IGBTs.
- Floating channel designed for bootstrap operation up to 600V.
- High output current drive capability (up to 2A peak).
- Undervoltage lockout protection for both high and low side.
- Fast switching speed with matched propagation delays.
- Logic input compatible with standard TTL and CMOS levels.
- Built-in dead-time control for safe switching operation.
- Low quiescent current for efficient performance.
- Compact 8-pin DIP or SOIC package for easy integration.
- Ideal for motor drivers, DC-DC converters, UPS, and power inverters.
