L2FET is a 5V gate-driven power MOSFET that is compatible with a 5V power supply for use in logic circuitry. L2FETs retain the on resistance, drain current, and blocking voltage ratings of their 10V predecessors, but operate from a much less costly 5V supply. The reduction in gate drive voltage is the result of halving the thickness of the gate insulator from the industry standard 100nm to 50nm (500Å). Since the surface inversion of the MOS channel is determined by the gate insulator voltage field, halving the insulator thickness halves the required gate voltage to achieve the same surface inversion, thereby not compromising drain characteristics.

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 FAN3111 1A gate driver is designed to drive an N-channel enhancement-mode MOSFET in low-side switching applications. It features a 1.4A peak current and 15ns delay time. It is suitable for switch-mode power supplies, synchronous rectifier circuits, pulse transformer drivers, logic to power buffers and motor control applications.

The FAN3121/FAN3122 is a single 9A high-speed, low-side gate driver from Fairchild Semiconductor Corporation. It has an industry-standard pinout with an enable input, a operating range of 4.5 to 18V, a peak sink of 11.4A at VDD = 12V, and a sink/source of 9.7A/7.1A at VOUT = 6V. It can be used in non-inverting and inverting configurations.

The FAN3268 is a 2A low-voltage PMOS-NMOS bridge driver that is optimized for driving high-side P-channel MOSFETs and low-side N-channel MOSFETs in applications such as motor control and buck converters.

FAN3278 is a 30V PMOS-NMOS bridge driver, suitable for motor control or buck step-down applications. It has an optimum operating range of 8V to 27V and drives high-side PMOS and low-side NMOS. The output drive voltage magnitude is limited to <13V and biases each load device off with a 100kΩ resistor when VDD is below the operating level. It has low-voltage TTL input thresholds and internal resistors that hold the driver off when no inputs are present. It is suitable for motor control, buck converters, and logic-controlled load circuits.
