LTC2900-2IMS#PBF

Supervisors Overview

The LTC2900-2IMS#PBF is a precision voltage monitor manufactured by Analog Devices Inc. It features three independent monitoring channels designed to supervise input voltages, including under-voltage and over-voltage conditions, as well as negative voltage monitoring. The device operates within a supply voltage range of 1.6V to 5.5V and draws a typical quiescent current of 30µA. It provides an open-drain reset output with a fixed 200ms reset delay time. The component is housed in a 10-lead MSOP package and is rated for operation between -40°C and +85°C.

Supervisors Feature Summary

• Supports simultaneous monitoring of three distinct voltage inputs
• Includes dedicated circuitry for negative voltage supervision
• Provides a single open-drain reset signal with defined timing

Supervisors Applications

• Supervising multiple power rails in embedded systems
• Monitoring battery voltage levels in portable devices
• Ensuring system integrity in industrial control equipment

Supervisors Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS standards. Confirm the IMS package variant matches the required footprint. Check official documentation for any recent product change notifications or lifecycle status updates before finalizing procurement plans.

Supervisors Selection Notes

Select this component when multi-channel supervision including negative voltage detection is required. Ensure the 200ms reset delay aligns with system startup requirements. Verify that the 1.5% accuracy specification meets the design tolerance needs for the monitored rails.

Supervisors Part Context

This part belongs to the LTC2900 series of supervisory circuits from Analog Devices. It is categorized under Power Management ICs (PMIC) specifically as a Voltage Monitor. The series is designed for applications requiring reliable power sequence management and fault detection across multiple voltage domains.

Supervisors Replacement Considerations

LTC2900-1IMS#PBF: Offers similar functionality but may differ in threshold configurations or channel capabilities. Verify pinout compatibility and electrical specifications against the original datasheet before substitution.
