LTC694CS8-3.3#TRPBF

Supervisors Overview

The LTC694CS8-3.3#TRPBF is a dual-channel power supply management circuit housed in an 8-pin SOIC package. It integrates voltage supervision, watchdog timer functionality, and battery backup switching for microprocessor systems. The device monitors input voltages with a threshold accuracy of 2% and provides a reset delay of 200 ms. It operates within a temperature range of 0°C to +70°C and draws a typical operating current of 600 µA. The component supports CMOS outputs and includes chip enable capabilities for system control.

Supervisors Feature Summary

• Integrates dual-channel voltage monitoring with fixed thresholds for comprehensive power supply supervision
• Includes built-in watchdog timer and battery backup switch for enhanced system reliability
• Features low quiescent current consumption suitable for energy-efficient designs
• Provides configurable reset timing and chip enable functionality

Supervisors Applications

• Microprocessor power supply monitoring
• Embedded system voltage supervision
• Battery-backed system protection
• Industrial control unit power management

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation as historical data may vary. Ensure the operating temperature grade matches your application requirements, as commercial variants differ from industrial grades. Cross-reference the exact part number with Analog Devices to confirm current production status and availability constraints.

Supervisors Selection Notes

Select this component when dual-channel supervision and integrated watchdog features are required in a compact surface-mount package. Compare against standalone supervisors if higher channel counts or adjustable thresholds are needed. Evaluate the 200 ms reset delay against system startup requirements. Consider the 600 µA operating current impact on overall system power budget during active states.

Supervisors Part Context

This part belongs to the LTC694 series of power supply management circuits designed for microprocessor applications. It consolidates multiple supervisory functions into a single IC, reducing board space compared to discrete solutions. The CS8 variant denotes the commercial temperature range and SOIC-8 package format commonly used in consumer and industrial electronics.
