Littelfuse releases IXD2012NTR high-side and low-side gate driver for high-frequency power applications

April 24, 2025 /SemiMedia/ — Littelfuse, Inc. recently announced the release of the IXD2012NTR, a high-speed, high-side and low-side gate driver designed to drive two N-channel MOSFETs or IGBTs in a half-bridge configuration. The IXD2012NTR is optimized for high-frequency power applications, delivering superior switching performance and enhanced design flexibility.

The IXD2012NTR operates over a wide 10 V to 20 V voltage range and supports a high side switch of up to 200 V in a bootstrap operation. Its logic inputs are compatible with standard TTL and CMOS levels down to 3.3 V, ensuring seamless integration with a wide range of control devices. With a 1.9 A source and 2.3 A sink output capability, the IXD2012NTR provides robust gate drive currents ideal for high-speed switching applications.

The device's integrated cross-conduction protection logic prevents the high- and low-side outputs from turning on simultaneously, while simplifying circuit design through a high level of integration. Offered in a compact SOIC(N)-8 package and operational over a temperature range of −40 °C to +125 °C, the IXD2012NTR delivers reliable performance even in harsh environments.
