MAX16133LFM+T

Supervisors Overview

The MAX16133LFM+T is a dual-channel voltage supervisor IC from the Automotive AEC-Q100 qualified MAX16133 series. It monitors two independent supply rails with threshold voltages of 1.2V and 3.3V. The device features an active-low reset output configured as open-drain or open-collector, ensuring reliable system reset signaling. It includes a minimum reset timeout of 50ms to prevent premature resets during power-up transients. The component operates within an extended temperature range of -40°C to 125°C and is housed in an SOT-23-8 package.

Supervisors Feature Summary

• Dual-channel voltage monitoring for independent supply rails
• AEC-Q100 automotive grade qualification for reliability
• Active-low open-drain/reset output configuration
• Extended industrial and automotive temperature operation

Supervisors Applications

• Automotive electronic control units (ECUs)
• Multi-rail power management systems requiring supervision
• Industrial equipment with strict reset timing requirements

Supervisors Procurement Notes

Verify the specific suffix 'LFM' against official Analog Devices documentation to confirm pinout and electrical characteristics match your design requirements. Ensure the source provides valid traceability for AEC-Q100 automotive grade components. Confirm the package type is SOT-23-8 before integration into PCB layouts.

Supervisors Selection Notes

Select this component when dual-supervision is required for automotive applications. The fixed thresholds of 1.2V and 3.3V limit flexibility compared to adjustable supervisors. Verify that the 50ms minimum timeout aligns with system startup sequences. Consider the open-drain output compatibility with downstream logic levels.

Supervisors Part Context

This part belongs to the MAX16133 family of low-voltage precision supervisors. The 'L' indicates specific threshold configurations, while 'FM' denotes the package and temperature grade. It is designed for robust performance in noisy environments typical of automotive and industrial sectors.

Supervisors Replacement Considerations

Check for direct cross-references in Analog Devices' replacement guides. Generic single-channel supervisors may not suffice due to the dual-monitoring requirement. Ensure any substitute maintains AEC-Q100 certification if used in automotive contexts.
