TPIC6A595DWR

Overview

The TPIC6A595DWR 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 pins to protect against inductive transients. It operates with a supply voltage range of 4.5V to 5.5V and supports a maximum operating temperature of 125°C.

Feature Summary

• Integrated low-side open-drain DMOS transistor outputs capable of sinking continuous current.
• Built-in voltage clamping structure provides protection against inductive transient spikes.
• Serial data cascading capability via dedicated serial output pin for multi-device expansion.

Applications

• Relay driver circuits
• Solenoid control systems
• Medium current or high voltage load switching

Procurement Notes

Verify the specific suffix 'DWR' corresponds to the SOIC-20 surface-mount package and tape-and-reel packaging configuration. Confirm RoHS compliance status and lead-free manufacturing details through official Texas Instruments documentation prior to procurement.

Selection Notes

Select this component when designing circuits that require driving inductive loads such as relays or solenoids directly from logic-level inputs. Ensure the application environment stays within the specified -40°C to 125°C operating temperature range and that the load voltage does not exceed the device's rated limits.

Part Context

This part belongs to the TPIC6 series of power shift registers manufactured by Texas Instruments. It serves as a bridge between standard digital logic interfaces and higher-power analog loads, offering integrated protection features that simplify PCB layout compared to discrete driver solutions.
