Infineon IRF7488TRPBF Dual N-Channel MOSFET: Key Features and Applications
The Infineon IRF7488TRPBF is a highly integrated dual N-Channel MOSFET packaged in a space-saving, thermally enhanced PG-TSDSON-8 (8-pin Dual Power-SO) package. This device is engineered to deliver superior performance in a compact form factor, making it an ideal solution for modern power management applications where board space is at a premium. By incorporating two independent MOSFETs in a single package, it simplifies circuit design, reduces component count, and enhances overall system reliability.
Key Features
The standout characteristics of the IRF7488TRPBF are centered on its efficiency, thermal performance, and integration.
Low On-Resistance (RDS(on)): With a maximum RDS(on) of just 9.5 mΩ at VGS = 10 V, this MOSFET minimizes conduction losses. This low resistance is crucial for improving energy efficiency and reducing heat generation in power-switching circuits.
Optimized for Low Voltage Drive: It is logic-level compatible, with a low gate threshold voltage, allowing it to be driven directly from 3.3 V or 5 V microcontrollers or DSPs without the need for additional gate drive circuitry. This simplifies design and lowers the total system cost.
Dual MOSFET Configuration: The integration of two N-Channel MOSFETs in a single package saves significant PCB area, which is critical for portable and miniaturized electronics.
High-Performance Package: The PG-TSDSON-8 package offers an excellent thermal-to-RDS(on) ratio. Its exposed pad provides efficient heat dissipation, enabling higher power handling capabilities and improved long-term reliability.
Fast Switching Speeds: The device is designed for high-frequency switching applications, which is essential for modern switch-mode power supplies (SMPS) and DC-DC converters to achieve higher power density.
Primary Applications
The combination of its key features makes the IRF7488TRPBF exceptionally versatile across a broad range of applications.
Synchronous Rectification in DC-DC Converters: It is a premier choice for synchronous buck and boost converters, particularly in point-of-load (POL) regulators for servers, telecom equipment, and computing motherboards. Its low RDS(on) directly enhances conversion efficiency.
Power Management Modules (PMICs): Widely used in battery-powered devices like smartphones, tablets, and laptops, where its small size and high efficiency help extend battery life.
Motor Control and Driving: Suitable for driving small DC motors in consumer electronics, robotics, and industrial automation systems, often in H-bridge configurations.
Load Switching: Ideal for high-side and low-side load switching applications, providing robust and efficient power distribution to various subsystems within a device.
