ADM6339GARJZ-RL7

Supervisors Overview

The ADM6339GARJZ-RL7 is a quad voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. It monitors four system supply voltages using internally pretrimmed undervoltage thresholds and provides an active low, open-drain reset output. The device features a manual reset input and a fixed 200 ms reset delay time. It operates within a supply voltage range up to 5.5 V and consumes 55 uA of quiescent current. The component is housed in a SOT-23-6 surface-mount package and functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Monitors up to four independent system supply voltages simultaneously
• Provides active low, open-drain reset signal with 200 ms delay
• Includes manual reset input for system control
• Low power consumption suitable for battery-operated applications

Supervisors Applications

• Microprocessor system power supervision
• Portable electronic devices requiring multi-voltage monitoring
• Industrial control systems with multiple power rails

Supervisors Procurement Notes

Verify the specific threshold voltage configuration for the GAR suffix against the official Analog Devices datasheet before procurement. Confirm availability status as distribution channels may list limited stock or end-of-life conditions. Ensure the SOT-23-6 package footprint matches your PCB design requirements. Check RoHS compliance documentation for regulatory adherence in your target market.

Supervisors Selection Notes

Select this component when simultaneous monitoring of four distinct voltage rails is required without external comparator circuits. The integrated manual reset feature allows for controlled system restarts. Consider the 55 uA quiescent current impact on overall system power budget. Verify that the available threshold options match the specific supply voltages present in your design architecture.

Supervisors Part Context

The ADM6339 series belongs to Analog Devices' family of precision quad voltage monitors designed for microprocessor supervision. These circuits replace discrete resistor networks and comparators, reducing board space and design complexity. The series offers various threshold combinations to accommodate different standard voltage levels commonly found in digital logic and memory systems.

Supervisors FAQ

Does the ADM6339GARJZ-RL7 include a watchdog timer?

No, the ADM6339GARJZ-RL7 does not incorporate a watchdog timer; it functions solely as a voltage supervisor with manual reset capability.

What is the reset delay time for this component?

The device features a fixed reset delay time of 200 ms after the monitored voltage falls below its threshold.
