LTC2900-1CMS#PBF

Supervisors Overview

The LTC2900-1CMS#PBF is a precision voltage monitor manufactured by Analog Devices Inc. It features three independent monitoring inputs with adjustable thresholds, housed in an MSOP-10 surface-mount package. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V and draws a typical quiescent current of 40 µA. It provides open-drain outputs for under-voltage, over-voltage, and negative voltage detection. The component includes a reset delay timer and functions within a commercial temperature range of 0°C to +70°C.

Supervisors Feature Summary

• Provides simultaneous monitoring for under-voltage, over-voltage, and negative voltage conditions via three distinct input channels.
• Features fully programmable threshold voltages allowing customization for specific system requirements without external resistors.
• Integrates a configurable reset delay timer to prevent false triggering during transient power events.

Supervisors Applications

• Portable battery-powered equipment requiring low standby current
• Industrial control systems needing multi-rail power supervision
• Embedded systems with strict voltage integrity constraints

Supervisors Procurement Notes

Verify the exact suffix against official Analog Devices documentation to confirm pinout and electrical specifications. Confirm RoHS compliance status through the manufacturer's datasheet. Check current availability as distribution may vary. Ensure the MSOP-10 footprint matches your PCB design constraints before ordering.

Supervisors Selection Notes

Select this component when multiple voltage rails require supervision using a single IC. It is suitable for applications where space is limited due to its compact MSOP-10 package. Consider the 40 µA quiescent current for battery life calculations. Verify that the required threshold ranges fall within the device's operational capabilities.

Supervisors Part Context

This part belongs to the LTC2900 series of precision voltage monitors designed for supervising multiple power supplies. It serves as a compact solution for detecting abnormal voltage conditions in complex electronic systems. The series is characterized by high accuracy and low power consumption, making it ideal for modern portable and industrial electronics.

Supervisors Replacement Considerations

Consult Analog Devices technical support or official cross-reference lists for verified substitutes. Ensure any replacement maintains the MSOP-10 package and functional compatibility. Do not assume interchangeability based solely on pin count.
