LTC2912HDDB-3#TRPBF

Supervisors Overview

The LTC2912HDDB-3#TRPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single under-voltage and over-voltage conditions. It operates within a supply voltage range of 1V to 6.5V and draws a typical quiescent current of 40µA. The device features an open-drain output and provides a reset timeout delay of 200ms. It is housed in an 8-lead DFN package (3x2mm) suitable for surface mount applications, with an operating temperature range spanning from -40°C to +125°C.

Supervisors Feature Summary

• Monitors a single input voltage line for both under-voltage and over-voltage events
• Provides a low-active open-drain reset signal upon fault detection
• Operates with low quiescent current consumption for power efficiency
• Includes a fixed reset timeout delay to ensure stable system recovery

Supervisors Applications

• Portable battery-powered equipment requiring voltage supervision
• Embedded systems needing single-rail power integrity monitoring
• Industrial control units operating across extended temperature ranges
• Communication infrastructure ensuring stable logic supply levels

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the HDDB variant corresponds to the specified 8-lead DFN footprint for PCB layout compatibility. Ensure the supplier provides official documentation to validate the part number against Analog Devices manufacturing records before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor is required for cost-sensitive designs. Consider the 40µA quiescent current for battery life calculations. Verify that the 200ms reset delay aligns with system startup requirements. The wide operating temperature range supports deployment in harsh environments without additional thermal management.

Supervisors Part Context

This part belongs to the LTC2912 series of simple supervisors. It complements other variants like the LTC2912HDDB-1 and LTC2912HDDB-2, which share similar electrical characteristics but may differ in threshold configurations or packaging options. The series focuses on providing reliable power-fail detection for microprocessors and memory devices.

Supervisors Replacement Considerations

Direct substitutes include other LTC2912 variants such as LTC2912HDDB-1#TRPBF or LTC2912HDDB-2#TRPBF, provided the threshold voltages match the application requirements. Cross-reference pinouts and package dimensions to ensure mechanical compatibility during replacement.
