LTC2901-1CGN#PBF

Supervisors Overview

The LTC2901-1CGN#PBF is a programmable quad supply monitor manufactured by Analog Devices Inc. It features an open-drain or open-collector output and provides active-low reset functionality with a minimum timeout of 5ms. The device monitors four distinct voltage rails and offers sixteen selectable threshold combinations for flexible configuration. It operates within a temperature range of 0°C to +70°C and is housed in a 16-lead SSOP package measuring 3.90mm in width.

Supervisors Feature Summary

• Monitors four independent power supply voltages simultaneously
• Configurable with sixteen selectable voltage threshold combinations
• Provides active-low reset signal with adjustable timeout duration

Supervisors Applications

• Multi-rail power system supervision
• Embedded system voltage monitoring
• Industrial equipment power integrity verification

Supervisors Procurement Notes

Verify the specific suffix #PBF confirms lead-free compliance and RoHS status before procurement. Confirm the -1CGN variant matches the required commercial temperature range and threshold settings. Ensure the 16-SSOP footprint aligns with the target PCB layout constraints.

Supervisors Selection Notes

Select this component when simultaneous monitoring of four voltage rails is required without external comparator complexity. The integrated threshold selection simplifies design compared to discrete solutions. Verify that the open-drain output interface is compatible with the downstream logic levels of the microcontroller or processor being supervised.

Supervisors Part Context

This part belongs to the LTC2901 family of multi-supply supervisors. It serves as a centralized monitoring solution for systems requiring reliable detection of under-voltage and over-voltage conditions across multiple power domains, replacing multiple individual supervisor ICs.

Supervisors Replacement Considerations

LTC2901-1IGN#TRPBF is a verified alternative offering identical functionality in tape-and-reel packaging with an extended industrial temperature range.
