The FAN3100 is a single-channel 2A high-speed low-side gate driver with 3A peak sink/source current at VDD = 12V and a 4.5 to 18V operating range. It features dual-logic inputs that can be configured as non-inverting or inverting with an enable function. The driver has internal resistors that turn it off if there are no inputs. It has a typical rise time of 13ns and a typical fall-time of 9ns with a 1nF load. It offers a choice of TTL or CMOS input thresholds and utilizes MillerDrive™ technology for a propagation delay time under 20ns with input falling or rising. The driver is available in a 6-lead 2x2mm MLP or 5-pin SOT23 package and is rated from -40°C to 125°C ambient. It is suitable for switch-mode power supplies, high-efficiency MOSFET switching, synchronous rectifier circuits, and DC-to-DC converters.
The FAN3100 is designed to drive an N-channel enhancement-mode MOSFET in low-side switching applications by providing high peak current pulses during short switching intervals. It incorporates MillerDrive architecture to minimize switching loss while providing rail-to-rail voltage swing and reverse current capability.
The device offers dual logic inputs that allow configuration as non-inverting or inverting with an enable function. Internal resistors bias the inputs such that if they are left unconnected, the output is pulled low to hold the power MOSFET off. It is available in lead-free 2x2mm MLP and industry-standard SOT-23 packages.
