IXDI409PI

Overview

The IXDI409PI is a single-channel, low-side gate driver IC manufactured by IXYS Integrated Circuits. It features an inverting logic configuration and is 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 VIL/VIH thresholds of 0.8V and 3.5V respectively. It is housed in an 8-pin DIP package and functions across a junction temperature range of -55°C to 150°C.

Feature Summary

• Provides high-current 9A push-pull output stage for rapid switching of power devices
• Features inverting logic input compatible with standard digital control signals
• Supports wide supply voltage operation up to 35V for flexible system integration

Applications

• Driving IGBT modules in motor control inverters
• Switching N-channel and P-channel MOSFETs in power conversion circuits
• Low-side switching applications in industrial power supplies

Procurement Notes

Verify the specific suffix 'PI' indicates the 8-pin DIP package variant. Confirm the component status as discontinued with no official replacement from the manufacturer. Ensure compatibility with existing PCB footprints before finalizing procurement plans due to end-of-life status.

Selection Notes

Select this component when a low-side, inverting driver with 9A peak current capability is required. Verify that the 8-pin DIP package fits the mechanical constraints. Check that the 4.5V to 35V supply range aligns with the system design. Consider the inverting logic function relative to the control signal polarity.

Part Context

The IXDI409PI belongs to the IXDI series of ultrafast gate drivers from IXYS. It is part of a family of low-side drivers designed for high-speed switching applications. The PI suffix specifically denotes the through-hole DIP-8 packaging option, distinguishing it from surface-mount variants like the SI or YI packages within the same electrical specification family.

Replacement Considerations

Official sources state there is no direct replacement for this discontinued part. Designers must evaluate alternative gate drivers with similar 9A current ratings, low-side configuration, and DIP-8 packaging. Electrical pinout compatibility and thermal performance must be verified against potential substitutes.
