LTC2900-2IDD#PBF

Supervisors Overview

The LTC2900-2IDD#PBF is a programmable quad supply monitoring circuit designed for systems with up to four supply voltages. It features a common reset output and a manual reset input, with adjustable reset timing. The device allows selection of one of 16 preset or adjustable voltage monitor combinations via an external resistive divider connected to the SET pin. It operates within a supply voltage range of 2.7V to 5.5V and offers high accuracy monitoring capabilities in a compact 10-DFN package.

Supervisors Feature Summary

• Programmable configuration supporting up to four independent supply voltage monitors
• Adjustable reset timer functionality for customized system protection sequences
• Common push-pull reset output with manual reset input capability

Supervisors Applications

• Multi-rail power supply monitoring in embedded systems
• Voltage supervision for complex digital logic circuits
• System integrity monitoring in industrial control equipment

Supervisors Procurement Notes

Verify the exact suffix #PBF indicates lead-free compliance when sourcing. Confirm the IDD package variant matches your PCB footprint requirements. Ensure the specific sub-model number aligns with the required voltage thresholds and timing characteristics defined in the official datasheet before finalizing procurement orders.

Supervisors Selection Notes

Select this component when multiple voltage rails require simultaneous supervision with a single IC. The programmable nature allows customization without changing hardware. Consider the 10-DFN package size constraints and the need for external resistors to set monitoring thresholds during the design phase.

Supervisors Part Context

This part belongs to the LTC2900 family of programmable supply monitors from Analog Devices. It serves as a centralized solution for power management integrity, replacing multiple discrete supervisor ICs. The series is designed for applications requiring precise voltage tracking across several power domains simultaneously.

Supervisors Replacement Considerations

Direct substitutes include other parts from the LTC2900 family with different suffixes for package or temperature variations. Verify electrical compatibility and pinout alignment before substitution.
