LTC1536CMS8#TRPBF

Supervisors Overview

The LTC1536CMS8#TRPBF is a precision supervisory circuit manufactured by Analog Devices Inc., designed for monitoring multiple voltage rails in embedded systems. It features three independent voltage monitor channels housed in an MSOP-8 surface-mount package. The device supports threshold voltages of 3.3 V, 5 V, and adjustable levels to accommodate various logic families. It operates within a supply voltage range up to 7 V with a maximum operating temperature of +70 C. Key electrical characteristics include a reset delay time of 200 ms and high accuracy of 0.75%. The component draws a typical quiescent current of 40 uA and includes power-fail detection capabilities without requiring manual reset or watchdog timer functions.

Supervisors Feature Summary

• Provides simultaneous monitoring of three distinct voltage rails for comprehensive system supervision
• Offers flexible threshold configuration including fixed 3.3 V and 5 V options alongside adjustable inputs
• Integrates power-fail detection logic to signal voltage anomalies before critical failure occurs

Supervisors Applications

• PCI bus application voltage monitoring
• Multi-rail embedded system supervision
• Industrial control board power integrity verification

Supervisors Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when sourcing. Confirm the commercial grade temperature rating aligns with your operational environment requirements. Ensure the MSOP-8 footprint matches your PCB layout constraints. Cross-reference the manufacturer's latest datasheet for any pinout revisions or handling precautions specific to this batch code.

Supervisors Selection Notes

Select this component when designing systems requiring simultaneous oversight of three separate power domains. It is suitable for applications needing precise threshold detection with minimal standby current consumption. Consider the adjustable channel for custom voltage references where standard fixed thresholds are insufficient. Ensure the input voltage range covers all monitored rails within the specified 7 V limit.

Supervisors Part Context

This part belongs to the LTC1536 series of precision supervisors from Analog Devices. It shares the functional architecture with variants like the LTC1536CS8 but differs in packaging and reel specifications. The series is engineered for reliable voltage tracking in space-constrained designs utilizing small outline packages.

Supervisors Replacement Considerations

LTC1536CS8#PBF serves as a tube-packaged alternative within the same family.
