ISO5452DW

Isolators - Gate Drivers Overview

The ISO5452DW is a single-channel galvanically isolated gate driver from the ISO5452 series, manufactured by Texas Instruments. It features a SOIC-16 surface-mount package and operates within a temperature range of -40°C to +125°C. The device provides a maximum propagation delay of 110 ns, with rise and fall times of 18 ns and 20 ns respectively. It supports output currents of 2.5 A or 5 A and accepts supply voltages between 15 V and 30 V. Power dissipation is rated at 1.255 W, with a quiescent current of 2.8 mA.

Isolators - Gate Drivers Feature Summary

• Integrated DESAT protection for IGBT monitoring
• Split output configuration supporting Miller clamp functionality
• Dedicated fault output pin with reset capability
• Soft turn-off feature to manage switching transients

Isolators - Gate Drivers Applications

• Industrial motor drives
• Inverter systems
• Uninterruptible power supplies (UPS)
• High-voltage DC/DC converters

Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'DW' indicates the tube packaging format distinct from the 'DWR' reel variant. Confirm RoHS compliance status through official manufacturer documentation. Ensure design compatibility with the specified SOIC-16 footprint and thermal requirements before finalizing procurement decisions.

Isolators - Gate Drivers Selection Notes

Select this component when high common-mode transient immunity is required for single-channel isolation. The split output design facilitates robust Miller clamp implementation for sensitive MOSFET and IGBT applications. Consider the 5 A peak drive current capability for medium-power switching scenarios requiring reliable gate control.

Isolators - Gate Drivers Part Context

This part belongs to the ISO5452 family of high-CMTI isolated gate drivers. It shares core electrical specifications with variants like the ISO5452DWR but differs in packaging. The DW suffix specifically denotes the tube package option, contrasting with the tape-and-reel configuration of other series members.

Isolators - Gate Drivers Replacement Considerations

The ISO5452DWR serves as a direct functional substitute differing only in packaging format. Verify that the target application supports tube-based assembly processes if replacing the DWR variant with the DW version.
