LTC2903IS6-E1#TRMPBF

Supervisors Overview

The LTC2903IS6-E1#TRMPBF is a supervisory circuit manufactured by Analog Devices Inc., housed in a TSOT-23-6 package. It functions as a precision monitor with four independent voltage monitoring channels and an integrated power-on-reset generator. The device operates within a supply voltage range of 1.7V to 5.5V, drawing a typical quiescent current of 20µA. It features adjustable thresholds for the monitored rails and supports open-drain or push-pull reset outputs. The component is rated for operation across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides four independent voltage monitoring channels for precise system supervision
• Integrates a power-on-reset generator with configurable delay options
• Supports both open-drain and push-pull output configurations for flexible interfacing

Supervisors Applications

• Portable battery-powered equipment requiring low standby current
• Industrial control systems needing multi-rail voltage supervision
• Embedded computing platforms utilizing multiple logic voltage domains

Supervisors Procurement Notes

Verify the specific suffix E1 against official Analog Devices documentation to confirm threshold settings and output configuration. Confirm availability status through authorized distributors as supply levels may vary. Ensure the TSOT-23-6 footprint matches your PCB layout requirements before finalizing procurement.

Supervisors Selection Notes

Select this component when designing systems that require simultaneous monitoring of multiple voltage rails within a compact form factor. Consider the 20µA quiescent current for battery life optimization. Evaluate the need for open-drain versus push-pull outputs based on downstream logic compatibility and pull-up resistor constraints.

Supervisors Part Context

This part belongs to the LTC2903 series of supervisory circuits from Analog Devices. The series is designed for applications requiring reliable voltage monitoring in space-constrained environments. The IS6 designation indicates the commercial temperature grade variant packaged in a TSOT-23-6 outline, distinguishing it from other thermal grades or package types within the same functional family.

Supervisors Replacement Considerations

Consult Analog Devices datasheets for direct pin-compatible alternatives within the LTC2903 family. Verify that any substitute maintains the required number of monitoring channels and compatible output drive capabilities.
