LTC2903IS6-D1#TRPBF

Supervisors Overview

The LTC2903IS6-D1#TRPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for precise monitoring of four independent voltage inputs. It operates within a supply voltage range of 2.7V to 5.5V and features a low quiescent current of 20µA. The device is housed in a compact TSOT-23-6 surface-mount package, suitable for space-constrained applications. It provides reset output functionality with configurable thresholds, ensuring reliable system protection against under-voltage conditions across multiple rails.

Supervisors Feature Summary

• Monitors four independent input voltages simultaneously
• Provides precise supervisory functions with configurable thresholds
• Operates with ultra-low quiescent current for power efficiency

Supervisors Applications

• Multi-rail power supply monitoring in embedded systems

• Industrial control units needing multi-channel voltage tracking

Supervisors Procurement Notes

Verify the specific suffix D1 against official Analog Devices documentation to confirm threshold configurations. Confirm availability status as distribution channels may indicate limited stock or special order requirements. Ensure the TSOT-23-6 package variant matches your PCB footprint design constraints before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when simultaneous monitoring of four distinct voltage rails is required within a small form factor. Consider the 20µA quiescent current for battery-operated applications where standby power consumption is critical. Verify that the input voltage range aligns with your system's operating voltages and that the reset output polarity meets your microcontroller interface requirements.
