LTC694CN8#PBF

Supervisors Overview

The LTC694CN8#PBF is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.5V to 5.5V and monitors a single input channel with a fixed threshold of 4.5V. The device features a CMOS output type and includes a watchdog timer function along with battery backup switching capabilities. It provides a reset delay time of 200 ms and maintains an accuracy of 2%. The component is designed for through-hole mounting in an 8-PDIP package, supporting an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrated watchdog timer functionality for system reliability
• Battery backup switching capability for power continuity
• Fixed threshold monitoring with high accuracy

Supervisors Applications

• Microprocessor system supervision
• Power failure detection circuits
• Watchdog timer implementations

Supervisors Procurement Notes

Verify the specific suffix CN8 against the official datasheet to confirm the commercial temperature grade and PDIP-8 package configuration. Ensure compatibility with the required 4.5V threshold and 200ms reset delay for your design. Confirm RoHS compliance status as per the latest manufacturer documentation before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 4.5V threshold is required for single-channel voltage monitoring. It is suitable for applications needing integrated watchdog and battery backup functions without external components. Consider the through-hole packaging constraint and the specified operating temperature range during board layout and thermal analysis.

Supervisors Part Context

This part belongs to the LTC694 series of supervisory circuits from Analog Devices. It is distinct from other variants like the IN8 or HS6 packages which may differ in temperature range or pinout. The CN8 designation specifically indicates the commercial temperature grade and plastic dual in-line package format used in legacy or through-hole designs.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the LTC694 family that match the 4.5V threshold. Verify if upgraded versions with extended temperature ranges are available if environmental conditions exceed the commercial grade limits.
