LTC695CSW-3.3#TRPBF

Supervisors Overview

The LTC695CSW-3.3#TRPBF is a supervisory circuit manufactured by Analog Devices Inc., designed for complete 3.3V power monitoring and battery control applications. It integrates multiple critical functions including power-on reset, battery backup management, RAM write protection, power-fail alarms, and watchdog timer capabilities. The device operates within a specified temperature range and features an open-drain or open-collector output configuration suitable for interfacing with microprocessor systems requiring reliable voltage supervision.

Supervisors Feature Summary

• Integrates comprehensive 3.3V power monitoring and battery control functionalities
• Provides dedicated power-on reset generation for system initialization
• Includes hardware-based RAM write protection mechanisms
• Features integrated watchdog timer for fault detection

Supervisors Applications

• Microprocessor power supply supervision
• Battery backup system management
• Embedded system RAM protection circuits
• Watchdog timer implementations in industrial controllers

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing components. Confirm the operating temperature grade matches the CS designation requirements for your environment. Ensure compatibility with 3.3V logic levels for the open-drain output interface. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm current production status and availability constraints.

Supervisors Selection Notes

Select this component when a single IC solution is required for both power monitoring and battery management at 3.3V. It is appropriate for designs needing integrated RAM write protection and watchdog functionality without external discrete components. Consider the SOIC-16 package constraints for PCB layout. Evaluate if the fixed 3.3V threshold meets the specific voltage supervision needs of the target microprocessor.

Supervisors Part Context

This part belongs to the LTC694/LTC695 series of supervisory circuits from Analog Devices. These devices are engineered to provide robust power management features for embedded systems. The CSW variant denotes a commercial temperature range and SOIC-16 surface-mount package. The series is commonly used in consumer electronics and industrial equipment requiring reliable power sequencing and memory protection.

Supervisors Replacement Considerations

The LTC695CSW-3.3#PBF is available in tube packaging as a direct alternative. Verify that the pinout and electrical characteristics remain identical between the reel and tube variants before substitution.
