LTC2907CTS8#TRMPBF

Supervisors Overview

The LTC2907CTS8#TRMPBF is a precision dual supply monitor manufactured by Analog Devices Inc. It operates within a power supply range of 1 V to 7 V and features an open-drain output type. The device provides two monitored inputs with one pin-selectable threshold and one adjustable input. It includes a reset delay time of 200 ms and maintains an accuracy of 1.5%. The component functions without manual reset or watchdog timer capabilities, drawing a typical operating supply current of 50 uA. It is housed in an SOT-8 package and supports surface mount installation.

Supervisors Feature Summary

• Dual voltage monitoring capability with one configurable pin-selectable threshold and one fully adjustable input for flexible system supervision.
• Precision performance characterized by 1.5% accuracy and a fixed 200 ms reset delay to ensure stable power-up sequencing.
• Low-power operation design utilizing an open-drain output interface suitable for direct connection to microprocessor reset lines.

Supervisors Applications

• Monitoring critical power rails in embedded systems requiring precise voltage supervision
• Supervising battery-powered devices where low quiescent current consumption is essential
• Industrial control units needing reliable reset generation under varying load conditions

Supervisors Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical characteristics and packaging options. Confirm RoHS compliance status as indicated in current datasheets. Ensure compatibility with your board layout regarding the SOT-8 package dimensions. Check for any obsolescence notices or lifecycle changes directly from Analog Devices before finalizing procurement plans.

Supervisors Selection Notes

Select this component when dual-supply monitoring is required in a compact form factor. The combination of a pin-selectable threshold and an adjustable input allows for customized protection levels without additional external components. Consider the 50 uA supply current for battery life calculations and verify that the 1.5% accuracy meets your system's tolerance requirements.
