LTC1726HMS8-5#PBF

Supervisors Overview

The LTC1726HMS8-5#PBF is a triple supply monitor and microprocessor supervisory circuit manufactured by Analog Devices Inc. It features adjustable reset timing and an integrated watchdog timer for system protection. The device operates within a supply voltage range of up to 7 V and includes three monitored inputs with thresholds at 3.3 V, 5 V, and an adjustable level. It utilizes an active low open-drain output and functions reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Triple supply monitoring capability with dedicated channels for fixed and adjustable voltage thresholds
• Integrated watchdog timer function to detect software malfunctions or bus hangs
• Adjustable reset delay timing to accommodate specific power-up sequencing requirements

Supervisors Applications

• Microprocessor system supervision in industrial control units
• Power management monitoring in embedded computing platforms
• Safety-critical systems requiring reliable fault detection and reset generation

Supervisors Procurement Notes

Verify the exact part number suffix against official Analog Devices documentation to ensure correct package type and temperature rating. Confirm RoHS compliance status through current datasheets. Check authorized distributor availability as stock levels may vary. Ensure the selected variant matches the required input voltage thresholds and operating temperature range for the target application environment.

Supervisors Selection Notes

Select this component when a single IC solution is needed to monitor multiple power rails simultaneously. The adjustable reset threshold allows flexibility for non-standard voltage levels. Consider the open-drain output compatibility with the host processor's reset input logic. Verify that the watchdog timeout requirements align with the system's operational cycle times and noise immunity needs.

Supervisors Part Context

This part belongs to the LTC1726 series of supervisory circuits designed for robust system management. It complements other Analog Devices PMIC offerings by providing dedicated monitoring functions without complex configuration interfaces. The MSOP-8 package offers a compact footprint suitable for space-constrained designs requiring high reliability in power integrity monitoring.

Supervisors Replacement Considerations

Direct substitutes include the LTC1726ES8-5#PBF which shares identical electrical specifications but utilizes an SOIC-8 package instead of MSOP-8. Designers must account for pinout and physical dimension differences during board layout modifications. Other family members may offer similar functionality but require verification of threshold voltages and package compatibility.
