LTC2912CDDB-2#TRPBF

Supervisors Overview

The LTC2912CDDB-2#TRPBF is a single-channel supervisory circuit manufactured by Analog Devices Inc. It monitors one voltage rail and provides a reset signal when the monitored voltage falls below or exceeds user-defined thresholds. The device operates within a supply voltage range of 1.7V to 5.5V and draws a typical quiescent current of 40µA. It features an adjustable or selectable threshold voltage, a programmable reset timeout, and an open-drain output. The component is housed in an 8-lead DFN package and supports operation from -40°C to +85°C.

Supervisors Feature Summary

• Single-channel voltage monitoring with adjustable or selectable threshold levels
• Programmable reset timeout for customized delay requirements
• Low power consumption with 40µA typical quiescent current
• Open-drain reset output compatible with various logic families

Supervisors Applications

• Portable battery-powered equipment requiring low standby current
• Embedded systems needing precise voltage supervision
• Industrial control units operating in varying temperature environments
• Communication modules requiring reliable power-fail detection

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm the 'C' grade designation matches your required operating temperature range of -40°C to +85°C. Ensure the DFN-8 footprint aligns with your PCB layout constraints. Cross-reference the datasheet for exact electrical characteristics relevant to your application design.

Supervisors Selection Notes

Select this part for applications requiring a single voltage monitor with minimal quiescent current. The adjustable threshold feature allows flexibility in setting trip points without external resistors if configured correctly. Consider the open-drain output capability for interfacing with different logic voltages. Verify that the package size fits within your available board space constraints.

Supervisors Part Context

This component belongs to the LTC2912 series of supervisory circuits designed for simple reset and power-fail monitoring functions. It serves as a critical protection element in power management architectures, ensuring system stability during brown-out or over-voltage events. The series offers various package options and threshold configurations to suit diverse design needs.

Supervisors Replacement Considerations

LTC2912HDDB-2#TRPBF: Higher temperature grade variant (-40°C to +125°C). LTC2912IDDB-2#TRPBF: Industrial temperature grade variant. Verify pinout compatibility and electrical specifications before substitution.
