The IXD2012NTR has been optimised for high-frequency power applications, delivering improved switching performance and enhanced design flexibility.

The device 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.

Its 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 can operate in harsh environments.
