ADM691AANZ

Supervisors Overview

The ADM691AANZ is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It provides comprehensive power supply monitoring and battery control functions for microprocessor systems. Key electrical parameters include a maximum supply voltage of 5.5 V, a threshold voltage of 4.65 V, and an overvoltage threshold of 4.75 V. The device features a reset delay time of 200 ms and operates with a standby current of 100 uA. It supports a watchdog timer and battery backup switching. The component is housed in a PDIP-16 package and operates within a temperature range of -40 C to +85 C.

Supervisors Feature Summary

• Integrates complete single-chip solutions for power supply monitoring and battery control functions in microprocessor systems
• Provides precision voltage monitoring with automatic battery backup power switching capabilities
• Includes fast onboard gating of chip enable signals and CMOS RAM write protection

Supervisors Applications

• Microprocessor Systems
• Computers
• Controllers
• Intelligent Instruments
• Automotive Systems

Supervisors Procurement Notes

Verify availability status as the part may be subject to limited supply or factory special orders. Confirm that the PDIP-16 through-hole package matches your PCB design requirements. Ensure the 5V CMOS process compatibility aligns with your system's voltage levels. Check for RoHS compliance details if environmental regulations apply to your manufacturing process.

Supervisors Selection Notes

Select this component when a dedicated supervisory circuit with integrated watchdog and battery backup is required. The fixed 200 ms reset delay suits applications not needing programmable timing. The PDIP-16 package is suitable for through-hole assembly processes. Consider the 100 uA standby current for low-power design constraints.

Supervisors Part Context

The ADM691AANZ belongs to the ADM691A/ADM693A/ADM800L/ADM800M family of supervisory circuits. This family serves as an upgrade path for the MAX691A/93A/800M series. The ADM691A variant specifically offers precision voltage monitoring and watchdog functionality without manual reset inputs.
