IXDN402SI

Overview

The IXDN402SI is a dual low-side MOSFET gate driver manufactured by IXYS. It features two independent output channels, each capable of sourcing and sinking 2A of peak current. The device operates within a supply voltage range of 4.5V to 35V and supports CMOS and TTL logic inputs. Packaged in an 8-SOIC (CT-8) surface-mount format, it ensures fast switching with rise and fall times of approximately 18ns and 17ns respectively. Designed for robust performance, it functions reliably across an operating temperature range from -55°C to +125°C.

Feature Summary

• Dual-channel architecture providing independent control for two low-side MOSFETs
• High peak output current capability of 2A per channel for efficient switching
• Compatibility with standard CMOS and TTL logic input signals
• Wide operating supply voltage range supporting various system configurations

Applications

• Motor drive systems requiring precise low-side switching control
• Power supply circuits utilizing high-speed MOSFET topologies
• Inverter designs needing isolated or non-isolated gate driving solutions

Procurement Notes

Verify the specific suffix designation against official IXYS documentation to confirm pinout compatibility and electrical specifications. Confirm availability status as this component may be classified as obsolete or discontinued in certain regions. Request detailed datasheets to validate thermal characteristics and ensure compliance with intended application requirements before finalizing procurement decisions.

Selection Notes

Select this component when dual low-side driving is required with moderate peak current demands. Ensure the application logic levels match the CMOS/TTL input specifications. Consider thermal management capabilities given the SOIC package constraints. Evaluate if the 2A output current suffices for the target MOSFET gate charge requirements at the desired switching frequency.

Part Context

The IXDN402SI belongs to IXYS' family of high-speed MOSFET drivers, designed for applications demanding reliable switching performance. It complements other variants like the IXDI404SI which offers higher current ratings. This part specifically targets cost-sensitive designs requiring dual-channel functionality without the complexity of high-side drivers.

Replacement Considerations

Check for direct replacements such as the IXDI404SI for increased current capacity. Verify pin-to-pin compatibility with alternative dual low-side drivers from other manufacturers. Ensure that any substitute maintains similar propagation delay and output current characteristics to preserve circuit timing integrity.
