TPIC6B595DWG4

Overview

The TPIC6B595DWG4 is a 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 housed in a 20-pin SOIC package. The device supports an operating temperature range from -40°C to 125°C. It utilizes DMOS technology for its open-drain outputs, which are rated for 50V with a continuous sink current capability of 150mA per channel. The component includes internal voltage clamping for inductive transient protection.

Feature Summary

• Integrates an 8-bit serial-in parallel-out shift register paired with an 8-bit D-type storage register for data latching.
• Features low-side open-drain DMOS transistor outputs capable of sinking significant load currents.
• Includes built-in voltage clamping on output terminals to protect against inductive transient events.
• Provides a serial output pin to facilitate cascading multiple devices for expanded control applications.

Applications

• Driving relay coils in industrial control systems
• Actuating solenoids requiring moderate current loads
• Controlling other medium-current or high-voltage loads

Procurement Notes

Verify the specific suffix G4 indicates RoHS compliance and lead-free status as documented in official datasheets. Confirm the SOIC-20 package dimensions match design constraints. Ensure the logic family specifications align with system requirements before finalizing procurement orders.

Selection Notes

Select this component when driving inductive loads such as relays or solenoids that require integrated transient protection. The open-drain architecture suits applications needing external pull-up voltages up to 50V. Consider the thermal performance at elevated junction temperatures due to current derating characteristics inherent to the DMOS structure.

Part Context

This part belongs to the TPIC6B595 series of power shift registers from Texas Instruments. It shares functional similarities with variants like the TPIC6B595DWR but differs in packaging and compliance markings. The series is designed specifically for power driver applications where high voltage tolerance and current handling are critical.

Replacement Considerations

The TPIC6B595DWR is a documented substitute within the same product family. Verify pin compatibility and electrical specifications before substitution. Ensure the replacement variant meets the required environmental and regulatory standards for the target application.
