TPIC6B596DW

Overview

The TPIC6B596DW is an automotive-grade, high-voltage shift register from the Texas Instruments TPIC series. It features a serial-to-parallel architecture with eight bits of data storage and registered parallel outputs. The device utilizes open-drain outputs capable of driving loads up to 50V, making it suitable for direct control of inductive or resistive loads without external transistors. It operates within a supply voltage range of 4.5V to 5.5V and supports a maximum clock frequency of 10MHz. The component is housed in a 20-pin SOIC package and is rated for operation across an extended temperature range of -40°C to +125°C.

Feature Summary

• High-voltage open-drain outputs designed for direct load driving up to 50V
• Automotive qualification ensuring reliability under harsh environmental conditions
• Registered parallel outputs maintain stable data states during shifting operations

Applications

• Automotive exterior lighting control modules
• Inductive load switching in vehicle body electronics
• High-side or low-side driver interfaces for actuators

Procurement Notes

Verify the specific suffix 'DW' corresponds to the 20-pin SOIC package variant. Confirm automotive grade status through official TI documentation rather than distributor summaries. Ensure the design accounts for the 50V output capability and thermal dissipation requirements inherent to the SOIC-20 form factor.

Selection Notes

Select this component when an automotive-rated shift register with integrated high-voltage output drivers is required. It eliminates the need for external power transistors in low-to-medium current applications. Compare against the TPIC6C596 series if lower voltage ratings are sufficient, or the TPIC6A595 if a different pin count is needed.

Part Context

This part belongs to the TPIC family of high-voltage shift registers developed by Texas Instruments. The series is specifically engineered for automotive applications requiring robust performance and simplified bill-of-materials by integrating power stages directly into the logic IC. The DW suffix denotes the surface-mount plastic small-outline package.

Replacement Considerations

Direct replacements include other members of the TPIC6B596 family with compatible packages, such as the TPIC6B596DWR (tape and reel version). Verify pinout compatibility before substituting with non-series parts.
