LTC1727IS8-5#PBF

Supervisors Overview

The LTC1727IS8-5#PBF is a micropower precision triple supply monitor manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.2V to 5.5V and consumes only 15µA of quiescent current. The device features three independent voltage supervisors with adjustable reset thresholds, an open-drain active-low reset output, and an integrated watchdog timer with a fixed timeout period. Packaged in an 8-lead MSOP, it supports industrial temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Integrates three independent voltage monitoring channels for comprehensive power supervision
• Includes a built-in watchdog timer with a fixed timeout interval for system reliability
• Provides an open-drain active-low reset signal compatible with standard logic interfaces

Supervisors Applications

• Portable battery-powered equipment requiring low standby current
• Embedded systems needing multi-rail power supervision
• Industrial control units with watchdog protection requirements

Supervisors Procurement Notes

Verify the specific suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the IS8 variant corresponds to the 8-lead MSOP package type. Check current availability status as distribution may be limited or subject to allocation. Ensure the operating temperature range meets the application's environmental specifications.

Supervisors Selection Notes

Select this component when multiple voltage rails require simultaneous monitoring with minimal power impact. The fixed watchdog timeout suits applications where deterministic recovery times are acceptable. Consider the open-drain output capability for flexible pull-up voltage selection. Evaluate the 15µA quiescent current against strict energy budget constraints.
