LTC694CS8#PBF

Supervisors Overview

The LTC694CS8#PBF is a microprocessor supervisory circuit manufactured by Analog Devices Inc. in an SOIC-8 package. It operates within a supply voltage range of 3 V to 5.5 V and monitors a single input channel. The device features a CMOS output type, a watchdog timer, and battery backup switching capabilities. Key electrical parameters include a reset delay time of 200 ms, a threshold accuracy of 2%, and a typical operating supply current of 600 uA. It supports chip enable signals and power-fail detection without manual reset functionality.

Supervisors Feature Summary

• Integrated watchdog timer for system reliability monitoring
• Battery backup switch capability for continuous operation during power transitions
• Power-fail detection with configurable reset delay
• Chip enable signal support for low-power management

Supervisors Applications

• Microprocessor system supervision

Supervisors Procurement Notes

Verify the specific suffix and manufacturer details against official Analog Devices documentation before procurement. Confirm that the SOIC-8 package and CMOS output specifications match the target design requirements. Ensure compatibility with the required supply voltage range and temperature ratings. Cross-reference the part number with authorized distributors to confirm authenticity and availability status.

Supervisors Selection Notes

Select this component when a dedicated microprocessor supervisor with integrated watchdog and battery backup functions is required. Consider the 2% threshold accuracy and 200 ms reset delay for timing-sensitive applications. Evaluate the 600 uA supply current against system power constraints. Verify that the single-channel monitoring and CMOS output interface align with the target processor's reset input requirements.

Supervisors Part Context

The LTC694 series comprises microprocessor supervisory circuits designed to monitor voltage levels and provide reset signals. The CS8 variant denotes the commercial temperature range and SOIC-8 surface-mount package. This family integrates essential protection features such as watchdog timers and power-fail detection into a compact form factor suitable for space-constrained embedded designs.

Supervisors Replacement Considerations

Consult Analog Devices documentation for verified pin-compatible or functionally equivalent alternatives within the LTC69x family. Ensure any substitute maintains the same supply voltage range, package type, and supervisory features.
