IR2121,Low-Side MOSFET/IGBT Driver, 1A/2A Output Current, Current Limiting,DIP-8

The IR2121 is a high-speed low-side driver IC designed to drive N-channel MOSFETs and IGBTs efficiently. It features a built-in current limiting and fault detection circuit, ensuring protection against overcurrent conditions in power management applications. With its logic-compatible input, it can operate with CMOS or LSTTL outputs, down to 2.5V logic levels.

Equipped with a compact DIP-8 package, the IR2121 is ideal for through-hole mounting and applications requiring reliable low-side MOSFET or IGBT driving. Advanced features such as undervoltage lockout (UVLO) and current sense functionality make it suitable for demanding environments like power converters, motor control systems, and industrial electronics.
