TPIC6B596DWR

Overview

The TPIC6B596DWR is an automotive-grade, monolithic high-voltage, medium-current power 8-bit shift register designed for systems requiring relatively high load power. It features a serial-in parallel-out architecture with integrated voltage clamping for inductive transient protection. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports data transfer on the rising edges of shift register clock (SRCK) and register clock (RCK). It utilizes open-drain DMOS transistor outputs rated at 50 V with a continuous sink current capability of 150 mA per channel.

Feature Summary

• Integrated voltage clamping for inductive transient protection
• Open-drain DMOS outputs with 150 mA continuous sink current capability
• Automotive-grade reliability for harsh environments
• Serial cascading capability via dedicated serial output

Applications

• Relay driving circuits
• Solenoid control systems
• Medium current or high voltage load management

Procurement Notes

Verify that the specific order matches the automotive qualification requirements, as indicated by the product description. Confirm the package type corresponds to SOIC-20 for surface mount installation. Ensure the operating temperature range aligns with the specified -40°C to +125°C limits for your application environment. Cross-reference the datasheet for exact pinout configurations to prevent integration errors during PCB design.

Selection Notes

Select this component when high-side or low-side switching of inductive loads is required with significant current demands. The integrated protection features simplify design compared to discrete solutions. Consider the 150 mA per-channel limit against total thermal dissipation constraints. Verify compatibility with standard logic levels for SRCK and RCK inputs to ensure reliable data shifting without additional level-shifting circuitry.
