ADM1812-5ART-REEL7

Supervisors Overview

The ADM1812-5ART-REEL7 is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.7 V to 5.5 V and features a fixed reset threshold voltage of 4.63 V. The device provides a push-pull output and includes a manual reset input for system control. It incorporates a watchdog timer with a timeout period of approximately 1.25 seconds, which can be disabled via the /RESET pin. The component is housed in an SOT-23-3 package and supports operation across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrated watchdog timer with selectable timeout functionality
• Manual reset input for active system intervention
• Push-pull output driver for robust signal integrity
• Fixed threshold voltage monitoring for power stability

Supervisors Applications

• Microprocessor power supply supervision
• Embedded system reset generation
• Watchdog timer implementation in industrial controllers
• Battery-powered device power management

Supervisors Procurement Notes

Verify the exact suffix configuration against the manufacturer's current datasheet, as packaging variants may differ. Confirm availability status directly with authorized distributors, as this specific reel variant may have limited stock or discontinuation notices. Ensure the manual reset feature aligns with your system design requirements before procurement.

Supervisors Selection Notes

Select this component when a fixed 4.63 V threshold is required for single-supply monitoring. The integrated watchdog timer simplifies design compared to discrete solutions. Consider the SOT-23-3 package size constraints and the need for a manual reset input. Verify that the push-pull output capability meets the drive requirements of the downstream logic.

Supervisors Part Context

This part belongs to the ADM181x series of microprocessor reset circuits from Analog Devices. These devices are designed to provide reliable reset signals for digital systems under varying power conditions. The series typically offers various threshold voltages and package options to accommodate different application needs while maintaining low quiescent current consumption.

Supervisors Replacement Considerations

Check for ADM1812-5ARTZ-RL7 or ADM1812-5ART-REEL as potential equivalents. Verify pin compatibility and electrical specifications with alternative manufacturers such as Maxim Integrated or STMicroelectronics if sourcing from non-ADI suppliers.
