LTC2917CDDB-A1#TRPBF

Supervisors Overview

The LTC2917CDDB-A1#TRPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for voltage monitoring and system protection. It operates within a supply voltage range of 0.8V to 5.5V and features a low quiescent current of 30µA. The device provides two independently selectable under-voltage thresholds and an over-voltage threshold, along with a programmable watchdog timer with timeout reset functionality. It is housed in an ultra-small DFN-8 package (3mm x 3mm) suitable for space-constrained applications. The component supports manual or automatic reset generation and includes a fail-safe reset output.

Supervisors Feature Summary

• Dual independent under-voltage monitors with user-selectable thresholds
• Integrated watchdog timer with programmable timeout period
• Ultra-low quiescent current consumption for battery-powered systems
• Fail-safe reset output ensures system recovery from communication errors

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Industrial control systems needing reliable voltage supervision
• Embedded systems with watchdog timer requirements
• Battery-operated equipment where low standby current is critical

Supervisors Procurement Notes

Verify the specific suffix A1 corresponds to the desired threshold configuration and package variant. Confirm RoHS compliance status through official documentation. Check availability as distribution may be limited. Ensure the operating temperature range meets application requirements. Validate pinout compatibility during PCB design integration.

Supervisors Selection Notes

Select this component when dual under-voltage monitoring and watchdog functionality are required in a minimal footprint. Compare quiescent current specifications against other supervisory ICs for efficiency optimization. Consider the available threshold options to minimize external resistor networks. Evaluate package size constraints relative to board layout limitations.

Supervisors Part Context

This part belongs to the LTC2917 series of supervisory circuits from Analog Devices.
