The IR25603PBF is a high-performance gate driver for IGBTs and MOSFETs within power management integrated circuit (PMIC) devices. It is designed for a wide variety of applications and provides a single-input, single-output control interface. Its features include integrated control logic, protected logic inputs, level shifters, and fault latches. Additionally, the IR25603PBF has an adjustable dead time control, an adjustable short-circuit protection timer, multiple stall channels, and an integrated PWM output.

This IC is suited for IGBT and MOSFET gate driver applications in motor control, server, disk drive, telecom, white goods, and general industrial segments. It can effectively drive power switches with high-side or low-side gate voltages, allowing the user to set the desired maximum dead time and fault-proof current limitation.

The IR25603PBF\'s operational principle is based on an advanced H-bridge current control and muxing operating scheme. It has a built-in logic circuit, integrated shunt and current-sense resistors, as well as a wide range of digital logic levels that can be adjusted for different applications. The device also contains shunt and current-sense resistors for high-side or low-side outputs. Additionally, it has an adjustable delay between the turn-on and turn-off of the output.

The IR25603PBF\'s power-supply range is 8 to 36V and its switch gate-drive voltage range is -50 to +50V. It has a typical on-resistance of 1.5 Ω (at 15V and 25°C, Vgs = -10V). The device also has an adjustable drive voltage range of -6 to +6V for fast gate-drive switching. Further, it offers a wide temperature range from -40 to +150°C and an on-resistance variation of 1% over temperature.

The IR25603PBF is a very cost-effective solution for self-driven or variable-frequency motor control applications. This device is highly scalable due to its adjustable logic levels, maximum dead time and fault-proof current limitation features. Additionally, it also offers protection features such as a user-defined over-current, under-voltage, and overtemperature protection timer.

The IR25603PBF is an excellent choice for applications that require cost-effective, EMC and voltage-regulator compatible gate-driver devices. It offers robustness, flexibility, and scalability, allowing the user to adjust its functioning parameters. This device helps provide an optimal power-switching effect and enhance the system\'s longevity.
