Littelfuse — IX4341 and IX4342 MOSFET Gate Drivers

Littelfuse has launched the IX4341 and IX4342, dual 5 A low-side MOSFET gate drivers which support high-speed operation for use in high-frequency switch-mode power supplies, dc-dc converters, motor controllers and power converters. The IX4341 and IX4342 drivers’ propagation delay time is just 16 ns, while rise and fall times are 7 ns.

With the addition of these new IX434x gate drivers, this Littelfuse series now consists of dual non-inverting, dual inverting, and non-inverting and inverting input versions, providing OEMs with a comprehensive range of input logic options.

For designs requiring a drive current higher than 5 A, the two channels of the IX4340 and IX4341 devices can be paralleled to form a single 10 A driver.

A notable feature of the IX434x drivers is their compatibility with TTL and CMOS logic inputs, enabling direct interfacing with most controllers. Each output has an independent enable function and under-voltage lockout circuitry to ensure reliable and safe operation.

When the supply voltage falls below the required value, the gate driver output is maintained low, turning the external power component off.

The IX434x MOSFET gate drivers are available in a standard 8-pin SOIC, a thermally enhanced 8-pin SOIC, or a 3 mm x 3 mm MSOP package.
