Infineon IR25607STRPBF: A High-Performance 600 V Half-Bridge Driver IC

In the realm of power electronics, the demand for robust, efficient, and intelligent gate driver ICs is ever-increasing. The Infineon IR25607STRPBF stands out as a premier solution, engineered specifically for high-performance half-bridge configurations in applications such as motor drives, switch-mode power supplies (SMPS), and lighting ballasts. This driver integrates advanced functionality with high-voltage resilience, making it a cornerstone for modern power conversion systems.

A key feature of the IR25607STRPBF is its high-voltage technology, which allows it to operate with bootstrap voltages up to 600 V. This capability is crucial for driving both high-side and low-side N-channel MOSFETs or IGBTs in a half-bridge topology. The IC incorporates a floating channel design for the high-side driver, enabling it to function effectively even when the switching node is subjected to high voltage swings. This design simplifies the power architecture by eliminating the need for an isolated power supply for the high-side gate drive.

The device is renowned for its robust performance and protection features. It includes integrated dead-time control (typ. 1.2 µs) to prevent shoot-through currents, a common failure mode in bridge circuits. This built-in protection enhances system reliability by ensuring that both switches in the half-bridge are never conducting simultaneously. Furthermore, the driver exhibits exceptional noise immunity due to its high dV/dt immunity of ±50 V/ns, making it suitable for noisy switching environments. The logic inputs are compatible with standard CMOS and LSTTL outputs, down to 3.3 V, facilitating easy interfacing with microcontrollers or DSPs.

Another significant advantage is its efficient driving capability. The output drivers feature a high pulse current buffer stage designed for minimum driver cross-conduction. With a typical source/sink current capability of 290 mA and 600 mA, respectively, it can swiftly switch power transistors, reducing switching losses and improving overall system efficiency. The propagation delays are matched between the two channels, ensuring precise timing critical for high-frequency operation.

The IR25607STRPBF is housed in a compact 8-pin SOIC package, offering a space-saving solution without compromising on performance or isolation. Its operational voltage range for the low-side section is from 10 V to 20 V, providing flexibility in system design.
