LTC2900-1IDD

Supervisors Overview

The LTC2900-1IDD is a programmable quad supply monitor manufactured by Analog Devices Inc. It features four independent voltage supervisors with open-drain or open-collector outputs housed in a 10-DFN (3x3) package. The device monitors multiple power rails and provides reset signals with an adjustable reset timer pulse width. It operates within a temperature range of -40°C to 85°C and supports a reset voltage of 5V.

Supervisors Feature Summary

• Programmable quad supply monitoring for multiple voltage rails
• Adjustable reset timer pulse width functionality
• Open-drain or open-collector output configuration

Supervisors Applications

• Multi-rail power system supervision
• Embedded system reset management
• Industrial control board monitoring

Supervisors Procurement Notes

Verify the manufacturer designation, as Linear Technology is now part of Analog Devices Inc. Confirm the specific suffix #PBF indicates lead-free compliance and the IDD suffix denotes the 10-DFN package type. Ensure the datasheet matches the programmable quad supervisor specifications rather than other variants in the family.

Supervisors Selection Notes

Select this component when designing systems requiring simultaneous monitoring of four distinct voltage levels. The adjustable reset timer allows customization of reset pulse duration to meet specific microcontroller or FPGA timing requirements. Verify that the open-drain output architecture aligns with the target logic level and pull-up resistor configuration.

Supervisors Part Context

This part belongs to the LTC2900 series of precision quad supply monitors. While the base LTC2900 offers similar monitoring capabilities in different packages like SOT-23, the LTC2900-1IDD specifically utilizes the 10-DFN form factor. It serves as a dedicated supervisory circuit for complex digital systems requiring robust power integrity checks.

Supervisors Replacement Considerations

Direct substitutes include other parts from the LTC2900 family with compatible pinouts and electrical characteristics. Verify package compatibility and reset threshold settings before substitution. Cross-reference with Analog Devices documentation for equivalent multi-supervisor ICs if the exact part is unavailable.
