LTC2916IDDB-1#TRMPBF

Supervisors Overview

The LTC2916IDDB-1#TRMPBF is a voltage supervisory circuit manufactured by Analog Devices Inc. It monitors a single input voltage and provides a manual reset output with an open-drain configuration. The device features nine selectable threshold voltages, allowing for flexible over-voltage and under-voltage detection without external resistors. It operates within a supply voltage range of up to 5.5 V and maintains an accuracy of 1.5%. The component includes a fixed 200 ms reset delay timer and functions reliably across an industrial temperature range from -40°C to +125°C while consuming only 30 µA of quiescent current.

Supervisors Feature Summary

• Integrates nine factory-selected voltage thresholds to eliminate the need for external resistor dividers
• Provides a manual reset function with an open-drain output for system control
• Features low power consumption suitable for battery-operated applications
• Includes a fixed 200 ms reset delay timer to ensure stable power-up sequencing

Supervisors Applications

• Monitoring power rails in embedded systems requiring manual intervention
• Industrial control units operating in extreme temperature environments
• Portable electronic devices where low standby current is critical
• Telecommunications equipment power management subsystems

Supervisors Procurement Notes

Verify the specific suffix IDDB-1 against official Analog Devices documentation to confirm the selected threshold voltage combination. Ensure the DFN-8 package dimensions match your PCB footprint requirements. Confirm that the manual reset functionality aligns with your system's safety protocols, as automatic recovery is not supported by this variant.

Supervisors Selection Notes

Select this component when a single voltage rail requires supervision with precise threshold accuracy. The manual reset feature distinguishes it from auto-recovery supervisors, making it suitable for fault conditions requiring operator acknowledgment. Consider the 30 µA quiescent current for power-sensitive designs and verify compatibility with the 5.5 V maximum input limit.

Supervisors Part Context

This part belongs to the LTC2916 series of voltage supervisors designed for monitoring single or multiple power supplies. It shares the DFN-8 package form factor with other variants in the family but differs in threshold selection and reset behavior. The series supports various industrial and commercial temperature ranges, providing a standardized solution for power integrity monitoring in compact electronics.

Supervisors Replacement Considerations

LTC2916HDDB-1#TRPBF offers similar functionality with a different temperature grade and packaging format.
