LTC1536CS8#PBF

Supervisors Overview

The LTC1536CS8#PBF is a precision triple supply monitor designed for PCI applications, manufactured by Analog Devices Inc. It features three independent voltage monitoring channels with thresholds of 3.3 V, 5 V, and an adjustable input. The device operates within a power supply range of up to 7 V and maintains an accuracy of 0.75%. It includes a fixed reset delay time of 200 ms and draws a typical operating supply current of 40 uA. The component supports active high, active low, and open drain output configurations without manual reset or watchdog timer functions.

Supervisors Feature Summary

• Triple channel voltage monitoring capability supporting 3.3 V, 5 V, and adjustable thresholds
• High accuracy specification of 0.75% for reliable threshold detection
• Flexible output configuration options including active high, active low, and open drain states
• Low power consumption design with 40 uA operating supply current

Supervisors Applications

• PCI bus system supervision
• Multi-voltage rail monitoring in embedded systems
• Power failure detection circuits
• Microprocessor reset generation

Supervisors Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm RoHS compliance status and manufacturing date codes prior to integration. Ensure storage conditions adhere to moisture sensitivity level requirements to prevent package damage. Cross-reference ordering part numbers carefully to match the specific CS8 suffix and PBF lead-free designation required for the target application.

Supervisors Selection Notes

Select this component when precise monitoring of multiple distinct voltage rails is required within a compact SOIC-8 footprint. The integrated adjustable threshold allows flexibility for non-standard voltage levels alongside standard 3.3 V and 5 V lines. Consider the 200 ms reset delay and 0.75% accuracy against system timing constraints and tolerance requirements before finalizing the design choice.

Supervisors Part Context

This supervisory circuit belongs to the LTC1536 series of precision voltage monitors from Analog Devices. It is specifically engineered for applications requiring simultaneous observation of multiple power supplies, such as PCI-compliant hardware. The device integrates essential monitoring logic into a small surface-mount package, reducing board space compared to discrete solutions while maintaining high reliability standards.

Supervisors Replacement Considerations

Consult official Analog Devices documentation for direct pin-compatible alternatives within the same family. Verify that any substitute maintains identical threshold voltages and output logic polarity. Ensure thermal and electrical specifications match the original design constraints before implementing any cross-replacement.
