TL432BQDBVT

Overview

The TL432BQDBVT is an adjustable precision shunt regulator manufactured by Texas Instruments, designed for automotive applications. It operates within a voltage range of 2.495 V to 36 V and features an initial accuracy of ±0.5%. The device supports a maximum cathode current of 100 mA with a minimum operating current of 700 µA. It is housed in a SOT-23-5 (SC-74A) surface-mount package and is qualified under AEC-Q100 standards. The component functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards
• Adjustable output voltage capability spanning 2.495 V to 36 V
• High precision performance with ±0.5% initial accuracy

Applications

• Automotive power supply regulation circuits
• Battery management systems requiring precise voltage monitoring
• General-purpose adjustable voltage reference modules

Procurement Notes

Verify the specific suffix 'VT' corresponds to the SC-74A/SOT-23-5 package variant when sourcing. Confirm AEC-Q100 qualification status is required for your specific automotive application tier. Ensure compatibility with the 100 mA cathode current limit in your circuit design. Check for RoHS compliance documentation if environmental regulations apply to your manufacturing process.

Selection Notes

Select this component when automotive reliability and high precision are critical requirements. The wide operating temperature range makes it suitable for harsh environments. Compare against standard industrial versions if automotive certification is not mandatory. Consider the SOT-23-5 footprint constraints during PCB layout planning. Evaluate the 700 µA minimum current requirement to ensure stable operation at low load conditions.

Part Context

This part belongs to the TL432 family of adjustable precision shunt regulators. It shares functional similarities with the TL431 but offers optimized characteristics for specific applications. The 'Q' designation indicates automotive qualification, distinguishing it from commercial variants. It serves as a key component in Texas Instruments' portfolio for power management solutions.

Replacement Considerations

The TL432BQDBVR is a reel-packaged alternative within the same series. Verify pinout compatibility before substitution. Ensure the replacement maintains the required AEC-Q100 qualification level.
