TL432BQDBZR

Overview

The TL432BQDBZR is an automotive-grade adjustable precision shunt voltage reference from Texas Instruments, designed for robust power management applications. It operates within a supply voltage range of 2.495 V to 36 V and delivers an initial accuracy of 0.5%. The device features a temperature coefficient of 92 PPM/°C, ensuring stable performance across the industrial temperature range of -40°C to +125°C. With a maximum cathode current of 100 mA and AEC-Q100 qualification, it provides reliable regulation in compact SOT-23-3 packages.

Feature Summary

• AEC-Q100 qualified for automotive reliability standards
• Adjustable output voltage up to 36 V with 0.5% initial accuracy
• Low temperature coefficient of 92 PPM/°C for thermal stability
• High cathode current capability of 100 mA

Applications

• Automotive battery monitoring systems
• Industrial process control loops
• Precision power supply references
• Voltage regulation in harsh environments

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the part number matches the exact suffix QDBZR for automotive grade and reel packaging specifications. Ensure compliance with RoHS directives and check for any recent product change notices affecting pinout or electrical characteristics before final procurement integration.

Selection Notes

Select this component when high precision and automotive durability are required. The 0.5% accuracy suits tight tolerance designs. Compare against TL432 variants if lower cost or different package options are needed. Consider the 100 mA current limit for load requirements. Verify thermal management needs given the wide operating temperature range.

Part Context

Part of the TL432 family of adjustable shunt regulators, offering enhanced automotive reliability compared to commercial counterparts. It shares functional similarities with the TL431 but utilizes a different pin configuration suitable for specific layout constraints. The BQ suffix indicates automotive qualification and specific manufacturing standards.

Replacement Considerations

TL432BQDBZRG4 serves as a direct replacement with identical electrical specifications and automotive qualification. Ensure pin compatibility during substitution due to potential package marking differences. Verify that the alternative maintains the same 0.5% accuracy and 100 mA current rating.
