IR25606SPBF Application Field and Working Principle

PMIC - Gate Drivers

The IR25606SPBF is an advanced gate driver IC based on international rectifier’s latest technology featuring active Miller clamp, high and low side protected outputs, and shoot-through protection. It is specifically designed to provide the required driving voltage when driving large MOSFETS, IGBTs and other devices operating in the power range. Thanks to the active Miller clamp, output drives can be protected against short-circuit and shoot-through conditions.

The IR25606SPBF offers the integration of sensing and regulation of both the high and low side drives. The high side output and low side output are internally protected against over-voltage and under-voltage, thus preventing damage to the device during abnormal and undesired operation conditions.

The IR25606SPBF is specifically designed to provide an optimal gate drive solution for medium and large power MOSFETs, IGBTs and other devices, in the 400V to 600V voltage range. It is an ideal solution for a wide range of applications, such as Switch-mode Power Supplies, High Voltage DC-DC Converters, Lithium-ion Battery Chargers and High Voltage Motor Controls.

The IR25606SPBF works according to the rectangular wave oscillator principle. In this principle, the gate drive of a MOSFET is provided by an AC current source. The AC source is then driven by an oscillator at a certain frequency. The oscillator produces an AC waveform, which is then filtered and amplified. The filtered and amplified signals are then sent to the drain of the MOSFETs as a gate drive. The gate drive switching can then be controlled and regulated to achieve the desired output voltage and current.

The IR25606SPBF is a highly advanced device, which combines the advantages of the active Miller clamp, high and low side protected outputs, and shoot-through protection. This allows the device to provide reliable, robust and efficient gate drive solution for medium to large power MOSFETs, IGBTs, and other semiconductor devices operating in the 400V to 600V range. The active Miller clamp also provides enhanced protection that helps to ensure the safe and reliable operation of the MOSFETs, IGBTs and other semiconductor devices.

In conclusion, the IR25606SPBF is an ideal solution for customers looking for an advanced gate driver IC that offers robust protection features, efficient performance and a wide range of applications. It is well suited for switch-mode power supplies, high voltage DC-DC converters, lithium-ion battery chargers and other high voltage motor control applications.
