ADM6318CZ28ARJ-RL7

Supervisors Overview

The ADM6318CZ28ARJ-RL7 is a supervisory circuit from Analog Devices designed for microprocessor-based systems. It monitors power supply voltage levels and code execution integrity. The device features a fixed reset threshold voltage of 2.8V with an accuracy of 2.5%. It includes a watchdog timer with a typical timeout of 1600 ms and offers a manual reset input. The output stage is push-pull active low, ensuring valid reset signals down to VCC = 1 V. Operating current is typically 5 μA. It is housed in a 5-lead SOT-23 package and operates within an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for code execution monitoring alongside voltage supervision
• Includes a dedicated manual reset input for external system control
• Provides push-pull active low reset output stage for direct logic interfacing
• Ensures power supply glitch immunity and reliable operation at low voltages

Supervisors Applications

• Microprocessor systems
• Controllers
• Intelligent instruments

Supervisors Procurement Notes

Verify the specific suffix ARJ-RL7 against the manufacturer's official documentation to confirm reel packaging and tape width specifications. Ensure the component meets the required industrial temperature range and RoHS compliance status for your target application environment before finalizing procurement orders.

Supervisors Selection Notes

Select this part when a push-pull active low output is required for direct interface with digital logic without additional pull-up components. The fixed 2.8V threshold suits 3.3V or 5V systems requiring precise supervision. Consider the 1600 ms watchdog timeout duration relative to the processor's instruction cycle to ensure proper fault detection timing.

Supervisors Part Context

This component belongs to the ADM6316/ADM6317/ADM6318/ADM6319/ADM6320/ADM6321/ADM6322 family of supervisory circuits. These devices share common features such as low power consumption and multiple reset threshold options but differ in output stage configurations and the presence of watchdog or manual reset inputs. The ADM6318 specifically combines watchdog functionality with a push-pull output.
