ADM6339EARJZ-RL7

Supervisors Overview

The ADM6339EARJZ-RL7 is a quad voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. It monitors four independent supply voltages using internally pretrimmed undervoltage thresholds, specifically configured for 1.23 V, 2.05 V, 2.63 V, and 4.40 V inputs. The device features an active low, open-drain reset output with a fixed 200 ms reset delay time to ensure stable power-up sequencing. It operates within a supply voltage range up to 5.5 V and consumes a typical quiescent current of 55 uA. The component supports manual reset functionality via an external input and lacks watchdog timer or battery backup switching capabilities. It is housed in a compact SOT-23-6 surface-mount package and is rated for operation between -40°C and +85°C.

Supervisors Feature Summary

• Monitors four distinct voltage rails simultaneously using factory-trimmed undervoltage thresholds
• Provides a synchronized active low open-drain reset signal with a guaranteed 200 ms delay
• Supports manual system reset through a dedicated external input pin
• Operates with low quiescent current consumption suitable for power-sensitive applications

Supervisors Applications

• Multi-rail embedded system power supervision
• Microprocessor board voltage monitoring
• Industrial control unit power integrity verification
• Communication equipment power rail validation

Supervisors Procurement Notes

Verify the specific threshold configuration (EAR suffix) against design requirements before procurement. Confirm availability status as this part may be discontinued or limited. Ensure compatibility with the target PCB footprint and thermal management needs. Cross-reference the latest datasheet for any updated electrical characteristics or packaging changes.

Supervisors Selection Notes

Select this component when simultaneous monitoring of four specific voltage levels is required without complex programming. The fixed thresholds eliminate calibration needs but limit flexibility compared to adjustable supervisors. Consider the 200 ms delay constraint for system startup timing. Evaluate the SOT-23-6 package size against available board space constraints.

Supervisors Part Context

This component belongs to the ADM6339 family of quad voltage supervisors from Analog Devices. It shares the same core architecture and package style with variants like ADM6339PARJZ-RL7 and ADM6339AARJZ-RL7, differing primarily in the specific factory-set undervoltage thresholds for each monitored channel. The family targets general-purpose multi-supervision tasks in portable and industrial electronics.
