LTC2909CTS8-2.5#TRMPBF

Supervisors Overview

The LTC2909CTS8-2.5#TRMPBF is a precision triple/dual input voltage monitor manufactured by Analog Devices Inc., designed for supervisory applications in surface-mount designs. It operates within a supply voltage range of 1.7 V to 6 V and features an open-drain reset output with a fixed 200 ms reset delay. The device monitors three inputs, including under-voltage, over-voltage, and negative voltage conditions, with a typical accuracy of 1.5%. It is housed in an 8-pin SOT-23 package and functions reliably across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Monitors three distinct input channels for under-voltage, over-voltage, and negative voltage anomalies
• Provides a reliable open-drain reset signal with a fixed 200 ms delay to ensure system stability
• Operates efficiently with low quiescent current consumption suitable for power-sensitive designs

Supervisors Applications

• Portable electronic devices requiring precise power management
• Industrial control systems needing multi-channel voltage supervision
• Battery-powered equipment utilizing low-power monitoring circuits

Supervisors Procurement Notes

Verify the specific suffix 'CTS8' confirms the commercial temperature grade and SOT-23-8 packaging configuration. Ensure the '-2.5' designation aligns with the required threshold or reference settings for your circuit design. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement orders.

Supervisors Selection Notes

Select this component when designing systems that require simultaneous monitoring of multiple voltage rails without external comparators. The integrated precision and low power consumption make it suitable for space-constrained applications. Verify that the 6 V maximum supply voltage meets the system's operating requirements.

Supervisors Part Context

This part belongs to the LTC2909 family of precision voltage monitors from Analog Devices. The series is characterized by its ability to monitor up to three inputs using a single IC, reducing board space and component count. The CTS8 variant specifically denotes the commercial temperature range and compact SOT-23-8 footprint.

Supervisors Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Generic equivalents may not match the specific 1.5% accuracy or 200 ms delay characteristics.
