IR2011PBF

IR2011PBF Description

The IR2011PBF from International Rectifier is a high-performance dual-channel gate driver IC designed for driving MOSFETs and IGBTs in high-voltage applications. Operating within a 10V to 20V supply range, it features independent channels with inverting inputs, making it highly versatile for power electronics designs. With a peak output current of 1A (source/sink), it ensures robust switching performance, supported by fast rise/fall times (35ns/20ns typ) for efficient high-frequency operation. The device is housed in a through-hole package, facilitating easy integration into industrial and automotive systems.

IR2011PBF Features

• High-Side Voltage Capability: Supports bootstrap operation up to 200V, enabling high-side switching in half-bridge or full-bridge configurations.
• Fast Switching Performance: Optimized 35ns rise and 20ns fall times minimize switching losses, enhancing efficiency in high-frequency applications.
• Robust Drive Strength: 1A peak output current ensures reliable gate charging/discharging, even for large power devices.
• Wide Logic Compatibility: VIL = 0.7V, VIH = 2.2V ensures compatibility with TTL, CMOS, and microcontroller logic levels.
• Independent Channels: Allows flexible control of high-side and low-side switches in motor drives, inverters, and SMPS.
