IXDI409SIA

Overview

The IXDI409SIA is a low-side gate driver manufactured by IXYS. It features a single channel with an inverting input configuration, designed to drive IGBTs and N-channel or P-channel MOSFETs. The device operates within a supply voltage range of 4.5V to 35V. It delivers a peak output current of 9A for both sourcing and sinking. Typical rise and fall times are 10ns each. The component supports CMOS and TTL logic inputs with thresholds of 0.8V and 3.5V respectively. It functions reliably across a junction temperature range of -55°C to 150°C. The unit is housed in an 8-SOIC package.
