Power management integrated circuits (PMICs) are an important class of integrated circuits that ensure efficient use of power in applications including lighting, ballast controllers and more. The IRS2573DSTRPBF is a ballast controller from the well-known manufacturer Infineon that efficiently meets the needs of applications related to lamps in automobiles, aircraft, and other commercial or industrial lighting systems. The IRS2573DSTRPBF is designed to provide high reliability, wide input range operation, safe operation in fault conditions, and improved system performance.

The IRS2573DSTRPBF is a 3-channel, IGBT and MOSFET gate driver chip capable of providing up to 1.2A peak and 0.8A of continuous drive current. It contains integrated voltage step-down current limit and thermal shut-off protection features, allowing it to be used in multiple applications including lighting, ballast controllers, and more. It also features an internal power supply regulator and an adjustable gate drive delay circuit. This feature increases gate drive flexibility, allowing the chip to be used in several topologies such as half bridge and full bridge.

The main features of the IRS2573DSTRPBF include: a wide operating input voltage range of 5.5 to 15V; an adjustable dead-time control of up to 2.5µs; low on-resistance (Gsens) of 4mΩ for the high-side and 6mΩ for the low-side; an adjustable over-current protection of up to 4.3A; an integrated voltage step-down circuit; and a maximum turn-on voltage of only 1V.

The IRS2573DSTRPBF is an ideal choice for applications related to lighting, ballast controllers, and any power management system that needs highly reliable and cost-effective components. Thanks to its low on-resistance, its adjustable gate drive delay, and its adjustable over-current limit value, the IRS2573DSTRPBF can be used in multiple applications including automotive lamps, industrial and commercial lighting, and more.

The working principle of the IRS2573DSTRPBF can be divided into two different sections: one section that operates on the input power of the system, and the other section that directly controls the output driving of the IGBTs and MOSFETs of the device. The first section contains two power circuits: an energy storage unit, also known as the DCDC, and a simple bipolar protection circuit. The DCDC is responsible for the input filtering and system protection, while the bipolar protection circuit is responsible for driving the input power control.The second section directly controls the output driving. This section contains two power devices: a high-side MOSFET drive, and a low-side MOSFET drive. The gate driver chip is responsible for driving the gate and switching of both MOSFETs. The high-side MOSFET driver controls the switching of the high side MOSFET and the low side MOSFET driver is responsible for controlling the switching of the low side MOSFET. The gate driver chip also contains two delay circuits: the rising slew rate and the falling slew rate.

The IRS2573DSTRPBF is specially designed to meet the needs of applications related to lighting and ballast control. Its features are designed to ensure efficient operation, safe operation in fault conditions, and maximum reliability. Along with its integrated power supply and adjustable over-current limit value, the IRS2573DSTRPBF can be used in a variety of applications related to automotive lamps, industrial or commercial lighting, or any other power management application that requires reliable components.
