TPIC6B595DWRG4

Overview

The TPIC6B595DWRG4 is a monolithic high-voltage, medium-current power 8-bit shift register manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V and features nine output interfaces in a 20-pin SOIC package. The device supports an operating temperature range from -40°C to 125°C. Each output provides a continuous sink current capability of 150mA with a typical current limit of 500mA at 25°C. The outputs are rated for 50V and include built-in voltage clamping for inductive transient protection.

Feature Summary

• Integrated low-side open-drain DMOS transistors providing high current sinking capability for driving heavy loads.
• Built-in voltage clamping on output pins designed specifically for protecting against inductive transient events.
• Serial data shifting mechanism allowing cascading capabilities through the serial output pin for system expansion.

Applications

• Relay driver circuits requiring high voltage isolation and current handling.
• Solenoid control systems for industrial automation.
• Medium current or high voltage load switching applications.

Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance and lead-free status as per manufacturer documentation. Confirm the SOIC-20 surface mount package dimensions match PCB footprint requirements. Ensure thermal management strategies account for the 125°C maximum junction temperature during operation. Validate that the 50V output rating aligns with the specific load voltage specifications in the design.

Selection Notes

Select this component when designing systems that require direct driving of inductive loads such as relays or solenoids without external flyback diodes. The integrated current limiting provides additional device protection compared to standard logic shift registers. Consider the 150mA per channel rating to ensure adequate drive strength for the intended负载 while managing total power dissipation within the SOIC-20 package constraints.

Part Context

This part belongs to the TPIC6B595 family of power shift registers from Texas Instruments. It serves as a bridge between low-voltage logic controllers and high-power actuators. The DWR variant specifically denotes the tape-and-reel packaging format suitable for automated surface-mount assembly processes, distinguishing it from tube-packaged or through-hole alternatives like the PDIP version.
