LTC2902-2IGN#PBF

Supervisors Overview

The LTC2902-2IGN#PBF is a programmable quad supply monitor designed for systems with up to four power rails. It integrates one of sixteen preset or adjustable voltage monitor combinations within a single package. The device features an adjustable reset timer and watchdog functionality, providing comprehensive supervision for complex multi-voltage architectures.

Supervisors Feature Summary

• Programmable configuration supporting up to four independent supply voltage monitors
• Adjustable reset timer and integrated watchdog circuit for system reliability
• Flexible monitoring options including sixteen preset or user-adjustable voltage thresholds

Supervisors Applications

• Multi-rail server and storage system power supervision
• Industrial control units requiring redundant power monitoring
• Telecommunications infrastructure equipment with multiple voltage domains

Supervisors Procurement Notes

Verify the specific suffix #PBF confirms lead-free compliance and RoHS status against current manufacturer documentation. Confirm the -2 variant designation matches the required threshold specifications for your design. Ensure the SSOP-16 package footprint aligns with your PCB layout constraints before finalizing procurement.

Supervisors Selection Notes

Select this component when designing systems requiring simultaneous supervision of multiple voltage rails without external comparator complexity. The integrated programmability reduces bill-of-materials count compared to discrete solutions. Evaluate the available preset combinations against your specific rail voltages to determine if custom adjustment circuits are necessary for optimal margin control.

Supervisors Part Context

This part belongs to the LTC2902 family of supervisory circuits from Analog Devices. It serves as a specialized power management IC focused on voltage monitoring rather than regulation. The device complements other PMIC components by ensuring system stability through continuous oversight of critical power inputs in demanding electronic environments.

Supervisors Replacement Considerations

The LTC2901-2IGN#PBF is a documented alternative within the same product family offering similar quad monitoring capabilities. Verify functional equivalence regarding reset timing and watchdog features before substitution. Cross-reference pinouts and electrical characteristics to ensure compatibility with existing board designs.
