Infineon Technologies IR1155STRPBF

PFC IC Continuous Conduction (CCM) Adjustable 8-SOIC

The IR1155STRPBF is a power management integrated circuit developed by Infineon Technologies. It falls into the category of gate driver ICs, specifically designed to drive power MOSFETs and IGBTs with high precision and reliability. This chip comes in a 16 - SOIC (Small - Outline Integrated Circuit) package, which is not only compact but also highly suitable for surface - mount technology, making it convenient for integration into various electronic devices.

One of the most notable features of the IR1155STRPBF is its ability to handle high - voltage applications. It can operate with an input voltage range typically from 10V to 20V, which allows it to interface with a wide variety of power supplies. With a peak output current of up to 2A, it has sufficient drive capability to switch power devices efficiently. The chip features a low propagation delay, which is crucial for high - speed switching applications, ensuring accurate and timely control of the power devices. Additionally, it has built - in protection mechanisms such as under - voltage lock - out and shoot - through protection. The under - voltage lock - out function prevents the chip from operating under abnormal voltage conditions, safeguarding the connected power devices. The shoot - through protection helps avoid short - circuits between the high - side and low - side power switches, enhancing the overall system reliability.

Regarding its operating conditions, the IR1155STRPBF can function stably within a temperature range of - 40°C to 125°C. This wide operating temperature range makes it suitable for use in diverse environments, including harsh industrial settings and normal consumer electronics applications. Whether it's in an industrial motor control system operating in a high - temperature factory environment or a consumer power tool that may be used in a variety of ambient conditions, the IR1155STRPBF can maintain its performance.

When looking for alternative models, the FAN7390 is a viable option. It is also a gate driver IC. Similar to the IR1155STRPBF, it can drive power MOSFETs. However, the FAN7390 has a slightly different input voltage range, typically from 8V to 18V, and may have different characteristics in terms of propagation delay and output current capabilities. Another alternative is the LM5113. This chip offers features like adjustable dead - time control, which can be beneficial in applications where precise control of the switching sequence is required to prevent shoot - through situations more flexibly.
