Overview
The TL432LIAEDBZRQ1 is an automotive-grade adjustable precision shunt voltage reference manufactured by Texas Instruments. It operates within a supply voltage range up to 36 V and provides an adjustable output voltage. The device features an initial accuracy of 1% and a temperature coefficient of 63 PPM/C. It supports a maximum cathode current of 15 mA with a minimum operating current of 600 uA. The component functions reliably across an extended temperature range from -40°C to +150°C. It is housed in a compact SOT-23-3 surface-mount package, designed for high-reliability applications requiring stable voltage regulation under varying thermal conditions.
Feature Summary
- Automotive qualification ensuring reliability for vehicle electronics
- High-temperature operation capability up to 150°C
- Adjustable output voltage via external resistors
- Precision stability with low temperature coefficient
Applications
- Automotive power management systems
- Traction inverter designs
- Voltage monitoring circuits
- Battery management systems
Procurement Notes
Verify the specific suffix ED to confirm the exact tape-and-reel packaging configuration and marking details. Ensure the order matches the Q1 automotive grade requirement for functional safety compliance. Cross-reference the datasheet revision history for any recent pinout or electrical specification updates before finalizing procurement specifications.
Selection Notes
Select this component when automotive certification and extended temperature performance are mandatory. The 1% initial accuracy suits applications requiring tighter tolerance than standard references. Compare against TL432LIBEDBZRQ1 if higher 0.5% accuracy is needed, noting that both share similar thermal characteristics and package types for direct form-factor compatibility.
Part Context
This part belongs to the TL432LI-Q1 family of adjustable shunt regulators. It shares functional similarities with the TL431 series but utilizes a distinct pinout arrangement suitable for SOT-23 packages. The LI variant denotes specific accuracy and temperature drift characteristics optimized for industrial and automotive environments.
Replacement Considerations
TL432LIBEDBZRQ1 offers 0.5% accuracy instead of 1%. TL431LIAEDBZRQ1 shares identical electrical specs but requires pinout adaptation due to different internal architecture.
