Product Description

The IR2109SPBF is a robust Half-Bridge Driver IC designed for high-efficiency control of High-Voltage MOSFETs in power switching applications. Featuring a single input channel and two complementary output channels, it directly drives high-side and low-side N-channel MOSFETs in a half-bridge configuration. The IC operates over a wide voltage range of 10V to 20V for the logic section and supports high-voltage rails up to 600V, making it suitable for industrial motor drives, inverters, and switch-mode power supplies. With a temperature range of -40°C to +125°C, it ensures reliability in harsh environments. Key advantages include integrated dead-time control to prevent shoot-through, low propagation delays, and compatibility with fast-switching MOSFETs. A minor drawback is the requirement for an external bootstrap diode for high-side drive. Compact and efficient, the IR2109SPBF excels in applications demanding precise MOSFET gate control under high-voltage conditions.
