LTC2901-2CGN#PBF

Supervisors Overview

The LTC2901-2CGN#PBF is a programmable quad supply monitor manufactured by Analog Devices Inc. It integrates four independent voltage supervisors with adjustable reset and watchdog timers in a 16-lead SSOP package. The device monitors up to four external voltages, providing active-low open-drain or push-pull reset outputs when thresholds are exceeded. It features selectable threshold combinations and configurable timeout delays for robust system supervision.

Supervisors Feature Summary

• Integrates four independent voltage monitoring channels within a single compact package
• Features programmable reset and watchdog timer functions for flexible system control
• Supports multiple output configurations including open-drain and push-pull modes

Supervisors Applications

• Multi-rail power supply supervision in industrial equipment
• Processor supervisor circuits for embedded systems
• Watchdog timer implementation in communication modules

Supervisors Procurement Notes

Verify the specific suffix '2' indicates the correct threshold combination and package variant. Confirm the 'CGN' designation matches the commercial temperature range and SSOP package requirements. Ensure the '#PBF' suffix denotes lead-free compliance if required by assembly specifications. Cross-reference the datasheet for exact pinout compatibility.

Supervisors Selection Notes

Select this component when multi-channel voltage monitoring with integrated timing functions is required. Consider the available threshold combinations and output drive capabilities. Evaluate the package size constraints against the 16-SSOP footprint. Verify that the operating temperature range meets the application environment requirements.

Supervisors Part Context

This part belongs to the LTC2901 family of quad supply monitors. It shares functional similarities with other members like the LTC2901-1 and LTC2901-3, differing primarily in threshold settings and package options. The series is designed for comprehensive power management supervision in complex electronic systems requiring reliable fault detection.

Supervisors Replacement Considerations

Direct substitutes include other LTC2901 variants such as LTC2901-1IGN#PBF or LTC2901-3IGN#PBF, provided the threshold settings and package type are compatible. Verify electrical parameters and pinout alignment before substitution.
