LTC2934CDC-2#TRMPBF

Supervisors Overview

The LTC2934CDC-2#TRMPBF is an ultra-low power adjustable supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.7V to 5.5V and features a selectable reset threshold voltage. The device provides a push-pull active-low reset output and includes a manual reset input for system control. Packaged in an 8-lead DFN, it draws only 500nA of quiescent current, making it suitable for battery-powered applications requiring precise voltage monitoring.

Supervisors Feature Summary

• Ultra-low quiescent current consumption for extended battery life
• Adjustable reset threshold voltage via external resistor divider
• Manual reset input capability for system initialization control
• Push-pull reset output driver for robust signal integrity

Supervisors Applications

• Portable electronic devices requiring low standby power
• Battery-operated instrumentation systems
• Embedded controllers needing programmable voltage supervision
• Industrial equipment with strict power management requirements

Supervisors Procurement Notes

Verify the specific suffix TRMPBF indicates tape-and-reel packaging when ordering. Confirm the DFN-8 package dimensions match your PCB footprint design. Ensure the selected reset threshold aligns with your target supply voltage using the manufacturer's calculation tools. Check for RoHS compliance documentation if required by your assembly standards.

Supervisors Selection Notes

Choose this component when adjustable thresholds are necessary rather than fixed-voltage supervisors. Consider the 500nA current draw against other options if ultra-low power is critical. Verify that the DFN-8 package fits your available board space. Compare performance against the LTC2935 series if multiple channels or different accuracy levels are needed.

Supervisors Part Context

This part belongs to the LTC2934 family of supervisory circuits designed for low-power applications. It complements other Analog Devices PMIC solutions by providing flexible voltage monitoring without significant power overhead. The DFN package offers a compact form factor suitable for modern miniaturized electronics designs.

Supervisors Replacement Considerations

The LTC2934ITS8-2#TRPBF serves as a pin-compatible alternative in an SOT-23-8 package. Verify thermal performance differences between DFN and SOT-23 packages during substitution. Ensure the reset threshold configuration remains consistent across both variants.
