FAN3225TMPX

The FAN3225TMPX by On Semiconductor is a dual gate driver designed for driving N-channel enhancement-mode MOSFETs in low-side switching applications. It offers a wide operating voltage range of 4.5V to 18V and delivers high peak current pulses, with a peak sink/source current of 5A at VDD = 12V. The device features matched internal propagation delays between channels, enabling critical timing applications like synchronous rectifiers. It also supports paralleling channels to double the current capability for driving a single MOSFET.

The FAN3225TMPX incorporates MillerDrive technology for its output stage, combining bipolar and MOSFET elements to provide high current during the MOSFET turn-on/turn-off Miller plateau. This minimizes switching loss and offers rail-to-rail voltage swing with reverse current capability. The driver is available with either TTL or CMOS input thresholds and includes an under-voltage lockout function. It comes in an 8-lead WDFN exposed pad package (3x3mm MLP) suitable for surface mounting.

Key electrical characteristics include a 4.3A sink and 2.8A source current at VOUT = 6V, and typical rise/fall times of 12ns/9ns with a 2.2nF load. The operating temperature range is -40°C to 125°C (TA). The device is designed for applications such as switch-mode power supplies, high-efficiency MOSFET switching, synchronous rectifier circuits, and DC-to-DC converters.
