ONSEMI FAN3111ESX High-Speed Gate Driver
The FAN3111 is a high-speed, low-side gate driver designed for driving N-channel MOSFETs in switch-mode power supplies, motor control, and other power switching applications. It offers dual CMOS inputs for inverting or non-inverting configurations, with a single low-voltage input for compatibility with low-voltage controllers. The device features an operating voltage range of 4.5 to 18 V, 1 A peak sink/source current, and a small 5-pin SOT23 package. Its fast rise/fall times, MillerDrive architecture, and separate high-current output paths enable efficient switching with minimal electromagnetic interference, suitable for distributed power networks and synchronous rectifiers.
