Overview

Description

The IR21531STRPBF is a high-voltage gate driver IC manufactured by Infineon Technologies. It is designed to drive N-channel MOSFETs in half-bridge configurations, commonly used in power conversion applications such as motor drives, power supplies, and lighting ballasts. The IC integrates a bootstrap diode and features high-side and low-side output drivers, enabling efficient switching and reducing external component count.
Key features include high voltage tolerance, with a maximum blocking voltage typically around 600V, and the ability to drive gates with a current capacity suitable for rapid switching. It offers under-voltage lockout (UVLO) protection for both high-side and low-side drivers to ensure reliable operation. The IC supports both bootstrap and charge pump methods for high-side biasing, making it versatile in different circuit designs.
With thermal shutdown protection and a wide operating temperature range, the IR21531STRPBF is durable and reliable. Its compact surface-mount package makes it suitable for space-constrained applications.
