IR2111 High-Low Side Gate Driver for Power MOSFETs / IGBTs

From the shop's description

IR2111 High-Low Side Gate Driver for Power MOSFETs / IGBTs 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.
