LTC2901-1CGN#TRPBF

Supervisors Overview

The LTC2901-1CGN#TRPBF is a programmable quad supply monitor manufactured by Analog Devices Inc. It features four independent voltage monitoring channels with open-drain or open-collector outputs and active-low reset signals. The device includes adjustable reset and watchdog timers, with a minimum reset timeout of 5ms. It supports 16 selectable voltage threshold combinations for flexible configuration. Operating within a temperature range of 0°C to 70°C, it is housed in a 16-lead SSOP package (3.90mm wide) designed for surface-mount installation.

Supervisors Feature Summary

• Provides four independent voltage monitoring channels with configurable thresholds
• Features adjustable reset and watchdog timers for system protection
• Delivers active-low reset signals via open-drain or open-collector outputs

Supervisors Applications

• Multi-rail power supply supervision in embedded systems
• Processor supervisor circuits requiring watchdog functionality
• Industrial control systems with multiple voltage domains

Supervisors Procurement Notes

Verify the specific suffix CGN against official Analog Devices documentation to confirm the commercial grade temperature rating and SSOP package variant. Ensure the TRPBF designation matches the required tape-and-reel packaging format. Cross-reference the full part number with current datasheets to validate availability status and any recent design changes or obsolescence notices before procurement.

Supervisors Selection Notes

Select this component when a quad-channel supervisory circuit with integrated watchdog timer is required. The 16 selectable threshold combinations allow adaptation to various voltage rails without external resistors. Verify that the 0°C to 70°C operating range meets the environmental requirements of the target application. Confirm compatibility with the system's logic levels given the open-drain/reset output structure.

Supervisors Part Context

This part belongs to the LTC2901 family of programmable quad supply monitors from Analog Devices. The series is designed for applications requiring comprehensive power management supervision. Variants within the family differ primarily in package type, temperature grade, and specific threshold configurations, while maintaining the core quad-monitoring and watchdog capabilities.
