LTC2911CDDB-3#TRPBF

Supervisors Overview

The LTC2911CDDB-3#TRPBF is a precision supervisory circuit manufactured by Analog Devices Inc., designed for monitoring multiple voltage rails in embedded systems. It features three independent voltage monitor channels with fixed thresholds, enabling comprehensive power integrity verification. The device operates within a supply voltage range of 1.7V to 5.5V and draws a typical quiescent current of 10µA, ensuring minimal impact on system efficiency. Packaged in an 8-pin TSOT-23 surface-mount format, it supports low-voltage applications requiring compact footprints. The component includes a push-pull reset output that asserts low when any monitored voltage falls below its respective threshold, providing reliable system protection against undervoltage conditions.

Supervisors Feature Summary

• Three independent voltage monitoring channels with fixed threshold settings
• Low quiescent current consumption for energy-efficient operation
• Push-pull reset output for robust signal driving capability
• Compact TSOT-23 surface-mount package design

Supervisors Applications

• Portable electronic devices requiring multi-rail power supervision
• Embedded microcontroller systems with strict size constraints
• Battery-powered equipment needing efficient power management
• Industrial control modules requiring reliable voltage monitoring

Supervisors Procurement Notes

Verify the exact part number including the suffix #TRPBF to ensure correct packaging configuration. Confirm that the fixed threshold voltages align with your specific application requirements before procurement. Check availability status as distribution may vary. Ensure compatibility with your PCB layout regarding the TSOT-23-8 footprint dimensions. Review the datasheet for thermal performance characteristics under expected operating conditions.

Supervisors Selection Notes

Select this component when three distinct voltage levels require simultaneous monitoring with fixed thresholds. Consider the 10µA quiescent current for battery life calculations. Evaluate the push-pull output stage if strong drive capability is needed compared to open-drain alternatives. Verify that the 1.7V minimum operating voltage suits your lowest supply rail. Assess the TSOT-23 package size against available board space constraints.

Supervisors Part Context

This part belongs to the LTC2911 series of supervisory circuits from Analog Devices. It shares functional similarities with other members like the LTC2911HTS8-1 but differs in package type and temperature grade specifications. The CDDB suffix indicates commercial temperature range operation in a TSOT-23 package. This series provides integrated solutions for complex power sequencing and monitoring tasks without external components.

Supervisors Replacement Considerations

LTC2911ITS8-1#TRMPBF offers similar functionality in the same package family with potentially different temperature ratings.
