LTC694IS8-3.3#TRPBF

Supervisors Overview

The LTC694IS8-3.3#TRPBF is a dual-channel power supply management circuit manufactured by Analog Devices Inc. It operates within an industrial temperature range of -40 °C to +85 °C and utilizes an 8-pin SOIC surface-mount package. The device provides fixed reset thresholds for two independent voltage channels, eliminating the need for external programming components. It functions as a supervisor circuit to monitor power rails and generate reset signals when voltages deviate from specified limits.

Supervisors Feature Summary

• Dual-channel architecture for simultaneous monitoring of two separate power supplies
• Fixed factory-set reset thresholds requiring no external resistor networks
• Compact 8-pin surface-mount packaging suitable for space-constrained designs

Supervisors Applications

• Industrial control systems requiring redundant power supervision
• Embedded computing platforms with multiple voltage domains
• Telecommunications equipment power rail monitoring

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging configuration. Confirm the manufacturer designation matches Analog Devices Inc. or Linear Technology legacy branding. Ensure the part number corresponds to the industrial temperature grade variant rather than commercial options. Cross-reference the datasheet revision date against current manufacturing notices to confirm active production status.

Supervisors Selection Notes

Select this component when fixed threshold supervision is preferred over programmable alternatives. The dual-channel design reduces bill-of-materials count compared to single-channel supervisors. Verify that the fixed trip points align with the target system voltage tolerances. Consider the SOIC-8 footprint compatibility during PCB layout planning to ensure proper thermal dissipation and signal integrity.

Supervisors Part Context

This part belongs to the LTC694 family of power supply management circuits designed for reliable voltage supervision.
