LTC2903IS6-B1#TRPBF

Supervisors Overview

The LTC2903IS6-B1#TRPBF is a quad supply monitor from Analog Devices, designed for precise voltage supervision in compact applications. It integrates four independent window supervisors within a single 6-lead TSOT-23 package. The device monitors external voltages against internal reference thresholds to detect out-of-range conditions. It features a dedicated reset output that asserts when any monitored channel exceeds its specified limits. The component operates with low quiescent current and supports various input voltage ranges suitable for portable and battery-powered systems requiring reliable power management.

Supervisors Feature Summary

• Integrates four independent precision window supervisors for comprehensive multi-rail monitoring
• Provides a combined active-low reset output indicating fault conditions across all channels
• Utilizes a compact 6-lead TSOT-23 surface-mount package for space-constrained designs

Supervisors Applications

• Portable electronic devices requiring multi-voltage supervision
• Battery-powered equipment needing efficient power management
• Industrial control systems with multiple logic rails

Supervisors Procurement Notes

Verify the specific suffix B1 against official Analog Devices documentation to confirm threshold configurations. Ensure compatibility with target voltage levels before integration. Check current availability status as distribution may vary by region. Confirm RoHS compliance details through manufacturer datasheets. Validate package markings against physical samples upon receipt.

Supervisors Selection Notes

Choose this component when simultaneous monitoring of four distinct voltage rails is required in a minimal footprint. Evaluate the fixed threshold options provided in the B1 variant against system requirements. Consider the low operating current for battery life optimization. Compare performance metrics with alternative supervisors if higher channel counts or adjustable thresholds are needed.

Supervisors Part Context

This part belongs to the LTC2903 series of supervisory circuits from Analog Devices. The series focuses on providing accurate voltage monitoring solutions for modern electronics. The IS6 designation indicates industrial temperature range operation within the TSOT-23-6 package format. The #TRPBF suffix denotes tape-and-reel packaging with lead-free composition.

Supervisors Replacement Considerations

LTC2903CS6-B1#TRPBF offers similar functionality with commercial temperature range specifications.
