IRS2302STRPBF is a high-performance gate driver IC for Power Management IC (PMIC): Gate Drivers applications. It is made with a compact design, yet provides eight outputs which can switch fast, making it ideal for driving Power Metal Oxide Semiconductor (Power MOS) or Insulated-Gate Bipolar Transistor (IGBT) devices for high power applications. The device combines on-chip protection and diagnostic features to facilitate a simplified high-performance power management system. This article discusses the application field and working principle of IRS2302STRPBF in detail.

Application Field

IRS2302STRPBF is widely used in multiple electric applications such as power stages, motor drives and solar power systems. It excels in demanding electric applications as it is capable of driver MOSFETs or IGBTs up to 600 Volt, with control frequency of up to 200KHz. Moreover, it features temperature and current monitoring and an integrated charge pump, cutting the need to build an external supply and reducing the system cost.

IRS2302STRPBF is also used in Multi-Phase Buck Converters (MPCs) and Phase Shift Modulators (PSMs) due to it’s high switching frequency and low power dissipation. Additionally, it is smoothly integrated in various Protection Systems such as Over- and Undervoltage, or Overload/Shortcircuit/Overcurrent. This allows for significant cost and size reductions.

Working Principle

The IRS2302STRPBF is a unique gate driver IC as it requires only one supply rail and an input reference. The device also features an integrated charge pump and logic bootstrap diodes to provide power to the high and low-side drivers.

The chip lowers power dissipation and system costs by utilizing a high-speed CMOS circuit for all signal processing operations. The protective functions of the IC are generated by a comparator circuit. It monitors the total current, the IC temperature and the input reference voltage.

IRS2302STRPBF also features fixed and adjustable dead-time control to ensure accurate power delivery. It is all done with less than one microsecond transitions and pulse-by-pulse current limiting at all temperatures.

In order to provide sufficient protection, the chip has built-in fault detection such as Undervoltage, Overvoltage and Overtemperature. The overtemperature detection is done by an external NTC thermistor. It shuts down the device by cutting off the signal lines with a three-state low side.

In summary, IRS2302STRPBF is a high-performance gate driver IC for PMIC: Gate Drivers applications, with high switching frequency, low power dissipation and fault detection capabilities. It is used in electric applications such as power stages, motor drives and solar power systems, as well as for Multi-Phase Buck Converters (MPCs) and Phase Shift Modulators (PSMs).
