LTC1326IMS8-2.5#PBF

Supervisors Overview

The LTC1326IMS8-2.5#PBF is a triple supply monitor from Analog Devices, designed for systems requiring precise voltage supervision. It features micropower operation with a typical quiescent current of 40 uA and operates within a supply range of 1 V to 7 V. The device provides three independent monitoring channels with fixed thresholds at 2.5 V, 3.3 V, and 5 V. It offers an open-drain reset output with a 200 ms delay and includes a chip enable pin for power management. Accuracy is specified at 0.75%, ensuring reliable detection of under-voltage conditions across the operating temperature range of 0°C to +70°C in an MSOP-8 package.

Supervisors Feature Summary

• Triple-channel voltage monitoring with fixed threshold options
• Micropower operation suitable for battery-backed systems
• Open-drain reset output with programmable delay
• Chip enable functionality for low-power control

Supervisors Applications

• Portable electronic devices requiring multiple voltage rails
• Battery-powered systems with backup power switching
• Embedded microprocessor supervisory circuits
• Industrial control systems with strict voltage tolerance requirements

Supervisors Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm RoHS compliance status and lot traceability prior to procurement. Ensure storage conditions adhere to moisture sensitivity level specifications to maintain device integrity. Cross-reference ordering information with official datasheets to confirm package type and suffix designations match project requirements.

Supervisors Selection Notes

Select this component when precise supervision of three distinct voltage levels is required in space-constrained designs. The fixed 2.5V/3.3V/5V thresholds simplify circuit design compared to adjustable alternatives. Consider the 40 uA quiescent current for efficiency-critical applications. Verify that the open-drain output interface aligns with the target system's logic levels and pull-up requirements.

Supervisors Part Context

Part of the LTC1326 family of triple supply monitors, offering precision supervision for multi-rail systems. The IMS8 variant denotes the MSOP-8 surface-mount package optimized for compact PCB layouts. This series supports applications demanding high accuracy and low power consumption without sacrificing monitoring reliability.

Supervisors Replacement Considerations

Direct substitutes include other triple-supply monitors from Analog Devices such as the LTC1326-2.5 variants with compatible pinouts. Verify electrical parameters and package dimensions before substitution. Alternative manufacturers may offer similar functionality but require thorough validation of threshold accuracies and timing characteristics.
