TPIC6A596DWR

Overview

The TPIC6A596DWR is a monolithic high-voltage, high-current power logic 8-bit shift register manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features an SOIC-24 package with 24 pins. The device supports serial-to-serial/parallel data transfer modes and includes built-in output clamp voltages for inductive transient protection. It functions as a single circuit with unidirectional shifting triggered on the rising edge, operating reliably across a temperature range of -40 °C to +125 °C.

Feature Summary

• Integrated output clamp voltage provides inherent protection against inductive transients
• High-current capability designed for systems with significant load power requirements
• Serial input with parallel output configuration simplifies interface connections

Applications

• Automotive lighting control systems
• Industrial motor driver interfaces
• High-power relay switching applications

Procurement Notes

Verify the specific suffix DWR indicates the tape-and-reel packaging variant when sourcing. Confirm that the component meets RoHS compliance standards if required for your assembly process. Ensure the SOIC-24 footprint matches your PCB layout constraints. Cross-reference the datasheet revision to confirm pinout consistency with existing designs.

Selection Notes

Select this component when driving inductive loads requiring high current without external clamping diodes. Consider the thermal performance of the SOIC-24 package under continuous load conditions. Evaluate the need for high-voltage tolerance if interfacing with automotive or industrial bus lines. Compare against lower-current variants if load requirements are modest.

Part Context

This part belongs to the TPIC6A series of power shift registers from Texas Instruments. These devices integrate DMOS outputs with standard logic shift register functionality. The series is engineered to reduce component count by combining shifting and driving capabilities in a single IC, suitable for replacing discrete transistor arrays in power management circuits.

Replacement Considerations

The TPIC6A596DW is the lead-free equivalent of this component. Verify pin compatibility before substitution. Other members of the 6A family may offer different pin counts or current ratings.
