LTC2917CMS-B1#TRPBF

Supervisors Overview

The LTC2917CMS-B1#TRPBF is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for low-voltage single-supply applications. It features selectable thresholds and an adjustable watchdog timer, housed in a compact MSOP-10 surface-mount package. The device monitors input voltages with high accuracy and provides open-drain output signals for system reset or alarm functions. Operating within a temperature range of 0°C to +70°C, it draws a typical supply current of 30 µA, ensuring efficient power management in portable and battery-operated electronics.

Supervisors Feature Summary

• Integrates selectable voltage thresholds for flexible monitoring configurations
• Includes an adjustable watchdog timer for automated system recovery
• Provides open-drain output signaling for interface compatibility

Supervisors Applications

• Portable electronic devices requiring low-power supervision
• Battery-operated systems needing under-voltage protection
• Embedded controllers utilizing watchdog functionality

Supervisors Procurement Notes

Verify the specific suffix B1 against official Analog Devices documentation to confirm threshold selection options. Ensure the MSOP-10 package dimensions match your PCB footprint requirements. Confirm RoHS compliance status through the manufacturer's latest material declaration before finalizing procurement specifications.

Supervisors Selection Notes

Select this component when multiple voltage thresholds are required without external resistors. The integrated watchdog timer simplifies design compared to discrete solutions. Verify that the 30 µA quiescent current meets system power budgets. Ensure the operating temperature range aligns with the intended environmental conditions.

Supervisors Part Context

This part belongs to the LTC2917 series of voltage supervisors from Analog Devices. It shares functional similarities with other members like the LTC2918 but differs in specific threshold configurations. The series is designed for cost-sensitive applications requiring reliable power monitoring in small form factors.

Supervisors Replacement Considerations

Consult Analog Devices documentation for direct pin-compatible alternatives within the LTC2917 family. Verify electrical parameters such as threshold accuracy and watchdog timing ranges before substituting.
