LTC2900-1CDD#TRPBF

Supervisors Overview

The LTC2900-1CDD#TRPBF is a programmable quad supply monitor manufactured by Analog Devices Inc. It simultaneously monitors up to four power supplies in systems requiring multiple voltage rails. The device features an adjustable reset timer and utilizes a single external resistive divider connected to a set pin to select from sixteen user-selectable combinations of standard voltages, including 1.5V, 1.8V, 2.5V, 3V, 3.3V, and 5V. Packaged in a 10-lead DFN with exposed pad (DFN-10), it operates within specified temperature ranges suitable for industrial applications.

Supervisors Feature Summary

• Simultaneously monitors up to four independent power supply voltages
• Configurable via a single external resistive divider network
• Adjustable reset timer functionality for flexible timing control

Supervisors Applications

• Multi-rail embedded systems monitoring
• Industrial control unit power supervision
• Automotive electronics voltage regulation verification

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm the DFN-10 package footprint matches the design layout. Ensure the selected voltage combination aligns with the target system requirements before finalizing procurement.

Supervisors Selection Notes

Select this component when simultaneous monitoring of four distinct voltage rails is required. The single-divider configuration simplifies board space compared to individual supervisors. Verify that the available preset voltage combinations cover all critical rails in the target application design.

Supervisors Part Context

This part belongs to the LTC2900 family of multi-supply supervisors. It serves as a centralized solution for complex power architectures where tracking multiple rails is necessary. The CDD package variant provides a compact surface-mount form factor for dense PCB layouts.

Supervisors Replacement Considerations

Direct replacements include other variants within the LTC2900 series such as the LTC2900-1IMS or LTC2900-1IDD, depending on the required package type and operating temperature range specifications.
