TPIC6A596DWRG4

Overview

The TPIC6A596DWRG4 is an automotive-grade, high-voltage shift register from Texas Instruments. It features a serial-to-parallel architecture with eight data stages and nine open-drain outputs capable of driving loads up to 100 mA each. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum clock frequency of 25 MHz. It includes a serial input, serial output for daisy-chaining, and parallel output enable functionality. The component is housed in a 20-pin TSSOP package and is rated for operation across an extended temperature range of -40°C to +125°C.

Feature Summary

• High-current open-drain outputs designed for direct drive of LEDs or other loads without external transistors
• Automotive qualification ensuring reliability under harsh environmental conditions
• Serial interface capability allowing cascading of multiple units for expanded I/O control

Applications

• Automotive exterior lighting systems including headlamps and tail lamps
• Interior ambient lighting and dashboard illumination control
• LED matrix displays and indicator arrays in vehicle cabins

Procurement Notes

Verify the specific suffix 'RG4' indicates RoHS compliance and green manufacturing status. Confirm the automotive grade designation aligns with your system's AEC-Q100 requirements. Ensure the TSSOP-20 footprint matches your PCB layout constraints. Check for any specific storage or handling guidelines related to moisture sensitivity levels defined in the datasheet.

Selection Notes

Select this component when high-side or low-side LED driving is required directly from logic signals. The open-drain configuration allows flexibility in connecting to various load types. Consider the thermal dissipation capabilities of the TSSOP package if driving multiple channels at full current simultaneously. Verify that the 5V logic interface is compatible with your microcontroller or driver IC.

Part Context

This part belongs to the TPIC6A596 family of high-voltage shift registers. It shares functional similarities with standard logic shift registers but integrates power drivers on-chip. The automotive variant ensures performance stability where standard industrial parts might fail due to voltage spikes or temperature extremes common in vehicle environments.

Replacement Considerations

Check for TPIC6A596DW variants which may differ only in packaging or reel specifications. Verify compatibility with TPIC6B596 series if latch functionality is preferred over shift register behavior. Ensure substitute parts maintain the same 100 mA output current rating and automotive qualification level.
