FAN3100CSX Description

Short technical summary and product information.

The FAN3100CSX is a high-speed, low-side gate driver from ON Semiconductor, designed to efficiently drive N-channel enhancement-mode MOSFETs in low-side switching applications. It provides high peak current pulses during switching intervals, with a 3A peak sink/source capability at 12V VDD. The device operates over a wide voltage range of 4.5V to 18V.

 

This gate driver features dual logic inputs that can be configured for non-inverting or inverting operation, along with an enable function. Internal circuitry includes an under-voltage lockout to ensure the output remains low until the supply voltage is within the operating range. The FAN3100CSX utilizes MillerDrive technology for optimized switching performance, minimizing switching loss while providing rail-to-rail voltage swing and reverse current capability.

 

Available in a compact SOT-23-5 package, the FAN3100CSX is suitable for applications requiring high-frequency power conversion and efficient MOSFET switching. Its typical rise time is 13ns and fall time is 9ns with a 1nF load, with propagation delays under 20ns. The device is rated for ambient temperatures from -40°C to 125°C.

 

Applications include switch-mode power supplies (SMPS), high-efficiency MOSFET switching, synchronous rectifier circuits, DC-to-DC converters, and motor control.
