TPIC6B595DW

Overview

The TPIC6B595DW is a monolithic high-voltage, medium-current power 8-bit shift register designed for systems requiring relatively high load power. It features an 8-bit serial-in parallel-out shift register and an 8-bit D-type storage register. The device includes built-in voltage clamping at the output terminals for inductive transient protection. It operates with a supply voltage range of 4.5V to 5.5V and supports data transfer on the rising edges of shift register clock (SRCK) and register clock (RCK). The outputs are low-side open-drain DMOS transistors rated for 50V with a continuous sink current capability of 150mA per channel.

Feature Summary

• Integrated voltage clamping for inductive transient protection
• Low-side open-drain DMOS transistor outputs
• Serial-to-parallel data shifting with storage register
• High-voltage tolerance for driving heavy loads

Applications

• Relay driver circuits
• Solenoid control systems
• Medium current load switching
• High voltage load driving applications

Procurement Notes

Verify the specific package suffix 'DW' corresponds to the SOIC-20 surface mount configuration when sourcing. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments. Ensure the ordering part number matches the exact functional requirements and pinout compatibility for your design implementation.

Selection Notes

Select this component for designs requiring direct drive of inductive loads without external flyback diodes. Consider the 150mA continuous current rating and 50V breakdown voltage for appropriate load matching. Evaluate thermal performance under simultaneous switching conditions if multiple channels are active concurrently.

Part Context

This device belongs to the TPIC6B595 family of power shift registers from Texas Instruments. It serves as a robust interface between low-voltage logic controllers and higher voltage/current actuators. The series is characterized by its integrated protection features and ability to handle significant electrical stress during switching events.

Replacement Considerations

Check for compatible alternatives such as the TPIC6A595 or other members of the 595 power shift register family. Verify pin compatibility and electrical specifications before substitution.
