FAN3226TMX-F085

The FAN3226TMX-F085 from On Semiconductor is a dual 2-A high-speed, low-side gate driver. It is engineered to drive N-channel enhancement-mode MOSFETs in low-side switching applications, delivering high peak current pulses during switching intervals. The device supports a wide operating voltage range of 4.5V to 18V and features TTL or CMOS input thresholds.

Key electrical characteristics include a 3A peak sink/source current at 12V VDD, and 2.4A sink/1.6A source current at 6V VOUT. It offers matched internal propagation delays between channels, enabling critical timing applications like synchronous rectifiers. The drivers incorporate MillerDrive technology for efficient MOSFET turn-on/turn-off, minimizing switching loss.

This gate driver is housed in an industry-standard 8-SOIC package, suitable for surface mount applications. It is rated for an operating temperature range of -40°C to 125°C (TA). The FAN3226 offers two inverting drivers, with dual independent enable pins that default to ON if not connected. Internal resistors ensure the driver turns off if inputs are left unconnected.

The FAN3226TMX-F085 is designed for applications requiring robust and precise gate driving. Its features make it suitable for various power conversion circuits where efficient switching and reliable operation are critical.
