LTC2903IS6-A1#TRPBF

Supervisors Overview

The LTC2903IS6-A1#TRPBF is a precision quad supply monitor manufactured by Analog Devices Inc. It monitors up to four independent supply voltages and provides a common reset output that remains low until all monitored inputs exceed their respective thresholds. The device operates within a voltage range of 2.7V to 5.5V and features a quiescent current of 20 µA. It is housed in a compact 6-lead TSOT-23 package, suitable for space-constrained applications requiring reliable power supervision.

Supervisors Feature Summary

• Monitors up to four independent supply voltages simultaneously
• Provides a common active-low reset output when all inputs are valid
• Low quiescent current consumption for battery-powered designs
• Compact 6-lead TSOT-23 surface-mount package

Supervisors Applications

• Portable electronic devices requiring multi-rail power supervision
• Embedded systems with multiple voltage domains
• Battery-operated equipment needing efficient power monitoring
• Industrial control systems requiring reliable reset generation

Supervisors Procurement Notes

Verify the specific suffix A1 matches the required threshold voltages and reset polarity for your design. Confirm the TRPBF designation indicates tape-and-reel packaging compatible with automated assembly processes. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the datasheet for exact electrical characteristics under your operating conditions.

Supervisors Selection Notes

Select this component when simultaneous monitoring of four distinct voltage rails is necessary. Consider the 20 µA quiescent current for low-power efficiency requirements. Evaluate the TSOT-23 package size against available PCB real estate. Verify that the input voltage range covers all monitored supplies without exceeding maximum ratings.

Supervisors Part Context

This part belongs to the LTC2903 series of precision quad supply monitors from Analog Devices. It is designed for applications requiring accurate supervision of multiple power rails in a small footprint. The series offers various options for different threshold voltages and package types to suit diverse design needs.

Supervisors Replacement Considerations

Direct substitutes include other parts from the LTC2903 family with matching pinouts and functionality. Verify equivalent threshold voltages and reset behavior before substitution. Alternative manufacturers may offer similar quad monitors but require careful parameter comparison.
