MAX16134QLA+T

Overview

The MAX16134QLA+T is an automotive-grade supervisory circuit designed for low-voltage, precision monitoring applications. It operates within a supply voltage range of 1.71V to 5.5V and draws a typical supply current of 12.5µA. The device supports single, dual, or triple channel configurations and features a factory-set reset threshold for voltages between 1.1V and 5V. It is qualified under AEC-Q100 standards and functions reliably across an operating temperature range of -40°C to 125°C (TA). The component is housed in an SOT-23-8 surface-mount package.

Feature Summary

• Provides robust power-system supervision suitable for safety-critical automotive environments
• Utilizes a factory-set reset threshold for accurate voltage monitoring without external components
• Delivers low-power operation with minimal supply current consumption

Applications

• Safety-critical automotive power system supervision
• General-purpose voltage sequence monitoring
• Single/dual/triple supervisor circuits in embedded systems

Procurement Notes

Verify the specific suffix 'QLA' and '+T' designation to ensure correct automotive qualification and tape-and-reel packaging configuration. Confirm that the source document explicitly identifies the part as AEC-Q100 qualified. Cross-reference the manufacturer's official datasheet for the MAX16134 series to validate pinout compatibility and electrical specifications against your design requirements before procurement.

Selection Notes

Select this component when automotive reliability and precise voltage monitoring are required. The fixed factory-set threshold eliminates the need for external resistors, simplifying board layout. Ensure the input voltage stays within the 1.71V to 5.5V operational range. Consider the SOT-23-8 package constraints for thermal management and space limitations in dense automotive PCB designs.

Part Context

This part belongs to the MAX16134 family of low-voltage supervisory circuits from Analog Devices/Maxim Integrated. The family includes variants supporting single, dual, and triple channels. The 'Q' prefix typically denotes automotive qualification, while 'LA' specifies the package and threshold characteristics. These ICs are categorized under PMIC supervisory circuits for critical system protection.

Replacement Considerations

Check for other MAX16134 variants with compatible thresholds and packages. Verify if alternative automotive-grade supervisors from the same manufacturer offer similar AEC-Q100 qualifications and supply current specs. Ensure any substitute maintains the SOT-23-8 footprint and functional equivalence for single/dual/triple supervision.
