IR25600STRPBF Integrated Circuits (ICs)

IR25600STRPBF is a gate driver integrated circuit (IC) that belongs to PMIC - Gate Drivers family. It is a high-voltage, high-current driver that is specifically designed to drive power MOSFETs and IGBTs in Bridgeless Totem Pole PFC and three-phase motor drive applications. Drivers of this type are capable of developing high output current and are particularly suitable for controlling power transistors in applications that are susceptible to transients such as motor speeds and lighting.

IR25600STRPBF is designed to drive both high-side and low-side power transistors. Its features include a sleep mode that minimizes power consumption, an integrated current sense amplifier, a fault monitor, and a low voltage drop surge-limiting capability. The driver can also be configured to operate in a push-pull configuration, and it offers four predefined output current levels.

IR25600STRPBF applications include driving IGBTs and MOSFETs in three-phase motor control applications, innovative dimming control designs, and automotive powertrain systems. The driver can also be used in maximum power point tracking (MPPT) and solar energy harvesting applications, such as those in the automotive, consumer electronics, and process control markets.

The working principle of IR25600STRPBF is based on its ability to provide both high-side and low-side drive capability for the power transistors. The low-side driver consists of two complementary transistors. The high-side driver consists of two power transistors in a push-pull configuration. The high-side gate voltage is level shifted using a built-in level translator. The level translator provides optical isolation of the two outputs and allows for a maximum gate voltage of up to 1700Vp.

The level translator also allows the user to select between two different drive current options. When operating the device in a push-pull configuration, the drive current can be selected depending on the output voltage requirements. The maximum drive current is 15A. In a pull-down configuration, the drive current can be adjusted up to 8A.

The IR25600STRPBF also features a sleep mode that reduces power consumption when the device is inactive. This is accomplished by disconnecting the drain of the low-side drivers and inhibiting the high-side drivers. In this mode, the device consumes less than 1.4 mW and is therefore suitable for energy efficient applications.

The driver also features an integrated current sense amplifier that can be used to measure the current through the power transistors. The amplifier has a gain of up to 65.5 and allows for precise current control and flexible power control algorithms. Additionally, the driver has a fault monitor that can detect current or voltage levels that are outside a predetermined range. The fault monitor can be used to protect the power transistors from over-voltage and over-current conditions.

In summary, IR25600STRPBF is a high-voltage, high-current driver that is specifically designed for driving IGBTs and MOSFETs in Bridgeless Totem Pole PFC and three-phase motor drive applications. Its features include a sleep mode that reduces power consumption, an integrated current sense amplifier for precise current control, and a fault monitor for detecting over-voltage and over-current conditions. This driver is suitable for a wide range of applications and can be used in automotive powertrain systems, innovative dimming control designs, maximum power point tracking (MPPT) and solar energy harvesting applications.
