LTC1536IS8#TRPBF

Supervisors Overview

The LTC1536IS8#TRPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for precise voltage monitoring in PCI applications. It features three monitored inputs with threshold voltages of 3.3 V, 5 V, and adjustable options. The device operates within a supply voltage range up to 7 V and consumes a typical operating current of 40 µA. It provides active high, active low, and open drain output types with a reset delay time of 200 ms. Accuracy is specified at 0.75%, and it lacks manual reset or watchdog timer functions. The component is housed in an SOIC-8 package and supports surface-mount installation.

Supervisors Feature Summary

• Monitors three distinct input voltages including fixed 3.3 V and 5 V thresholds alongside an adjustable channel
• Delivers multiple output configurations including active high, active low, and open drain signals
• Ensures high accuracy with a specified tolerance of 0.75% for reliable power supervision

Supervisors Applications

• PCI bus voltage monitoring systems
• Power failure detection circuits
• Embedded system supervisory logic

Supervisors Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape-and-reel configuration. Ensure the part number matches the exact pinout and electrical specifications required for the target design. Cross-reference the manufacturer's latest datasheet for any updates on material declarations or marking changes. Confirm availability status as distribution channels may indicate limited stock or special order requirements for this specific variant.

Supervisors Selection Notes

Select this component when multi-voltage supervision is required for standards like PCI. Consider the 40 µA quiescent current for battery-sensitive designs. Evaluate the need for manual reset or watchdog features, as this part does not include them. Compare the 0.75% accuracy against application tolerances. Verify that the SOIC-8 footprint fits the PCB layout constraints and that the 200 ms reset delay aligns with system startup timing requirements.

Supervisors Part Context

The LTC1536 belongs to Analog Devices' line of precision voltage monitor ICs. This series focuses on providing robust power management supervision for digital interfaces and embedded controllers. The IS8 variant specifically denotes the industrial temperature range and SOIC-8 packaging, distinguishing it from other thermal or package options within the broader LTC1536 family.
