IR2181S

The IR2181S is a high voltage, high-speed power MOSFET and IGBT driver designed by Infineon Technologies. It is specifically developed to cater to the needs of Class D audio amplifiers, where it can efficiently drive MOSFETs and IGBTs in half-bridge and full-bridge configurations. The driver IC offers several key features that make it stand out in the market. 1. High Voltage Capability: The IR2181S can provide a high voltage drive capability of up to 600V, making it suitable for a wide range of applications that require high voltage power switching, such as motor control and power supplies. 2. High-Speed Operation: With a maximum switching frequency of 1 MHz, the IC offers fast and precise switching for applications that demand high efficiency and low distortion. This makes it ideal for audio amplifiers as it can deliver high-quality sound reproduction. 3. Integrated Protection Functions: The IC incorporates a comprehensive range of protection features, including under-voltage lockout (UVLO), over-current protection (OCP), and thermal shutdown. These protections ensure the safe and reliable operation of the IC and the connected power devices. 4. Independent Input Control: The IR2181S has two independent input control pins, one for the high side and one for the low side. This allows separate control of the power devices in half-bridge or full-bridge configurations, enabling efficient power management and reducing cross-talk between the switching elements
