IR21531S, High-Voltage Half-Bridge Gate Driver, 600V, SOIC-8,SMD

The IR21531S - SMD is a high-voltage, self-oscillating half-bridge gate driver designed for driving both high-side and low-side MOSFETs or IGBTs. With a maximum offset voltage of 600V, this device is perfect for high-voltage power applications, including motor control, lighting ballasts, and high-power converters. The built-in oscillator simplifies the design of the gate driver, reducing the need for external control circuitry, while the integrated bootstrap diode further reduces component count and simplifies the design process.

Featuring undervoltage lockout protection, the IR21531S ensures reliable operation by preventing the gate driver from functioning at unsafe low supply voltages. This device also includes fast switching times, making it ideal for high-frequency applications. Packaged in a compact SOIC-8 form, the IR21531S is ideal for surface-mount applications that require space-efficient power solutions.
