LTC1536CS8#TRPBF

Supervisors Overview

The LTC1536CS8#TRPBF is a precision supervisory circuit designed for monitoring multiple voltage rails in PCI and general embedded applications. It features three independent input channels with selectable threshold voltages of 3.3V, 5V, or adjustable levels. The device provides active high, active low, and open drain output options to interface with various logic families. It operates from a single power supply ranging up to 7V with a typical quiescent current of 40µA. The unit includes a 200ms reset delay timer and lacks manual reset or watchdog functionalities.

Supervisors Feature Summary

• Monitors three distinct voltage inputs simultaneously
• Configurable threshold selection for standard system rails
• Flexible output drive capabilities including open drain

Supervisors Applications

• PCI bus voltage supervision
• Multi-rail power management systems
• Embedded controller power integrity checks

Supervisors Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm tape-and-reel packaging versus tube configuration. Ensure the selected variant matches the required threshold voltage options and output polarity for the target design. Cross-reference the manufacturer part number directly with the datasheet to avoid confusion with similar supervisory ICs.

Supervisors Selection Notes

Select this component when simultaneous monitoring of three voltage lines is required within a compact SOIC-8 footprint. Consider the 40µA operating current for battery-sensitive designs. Verify that the absence of a manual reset pin and watchdog timer aligns with the system's fault recovery strategy before finalizing the schematic.
