LTC2900-2CDD#PBF

Supervisors Overview

The LTC2900-2CDD#PBF is a supervisory circuit featuring two cascaded supervisors designed to monitor up to eight distinct voltage rails. It provides a common reset output and includes a manual reset input for system control. The device supports programmable reset timing, allowing customization of delay periods. It operates within a specified temperature range and utilizes a compact surface-mount package suitable for space-constrained designs.

Supervisors Feature Summary

• Dual supervisor architecture enables monitoring of multiple voltage channels through cascading
• Programmable reset timing allows adjustment of delay parameters
• Manual reset input provides direct user control over the reset state

Supervisors Applications

• Multi-rail power supply monitoring in embedded systems
• Processor supervision requiring multiple voltage thresholds
• Industrial equipment with complex power distribution networks

Supervisors Procurement Notes

Verify the specific suffix CDD indicates the package type and temperature grade. Confirm RoHS compliance status through official documentation. Ensure the part number matches the required pinout and electrical specifications for your design. Check availability constraints as supply may be limited.

Supervisors Selection Notes

Select this component when multiple voltage rails require supervision from a single IC footprint. The cascaded design reduces board space compared to using individual supervisors. Consider the manual reset feature if system recovery requires user intervention. Verify that the operating temperature range meets environmental requirements.

Supervisors Part Context

This part belongs to the LTC2900 family of quad supply monitoring circuits. The -2 variant specifically integrates two supervisors to expand monitoring capacity. Analog Devices manufactures this series for reliable voltage supervision in demanding applications.

Supervisors Replacement Considerations

LTC2900-2IMS#PBF offers similar functionality in an MSOP package. LT1236 is a related supervisor but lacks the multi-channel cascading capability. Verify pin compatibility before substitution.
