ADM803ZAKSZ-REEL7

Supervisors Overview

The ADM803ZAKSZ-REEL7 is a single-channel voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 1 V to 5.5 V and features a fixed reset threshold voltage of 2.32 V with an accuracy of 1.5%. The device provides an open-drain or push-pull output and includes a reset delay time of 240 ms. It functions without manual reset, watchdog timer, or battery backup switch capabilities. The component supports surface-mount installation in an SC-70-3 package and maintains operation across a temperature range of -40 °C to +125 °C while consuming 35 µA of operating current.

Supervisors Feature Summary

• Provides precise monitoring of power supply voltages using a fixed threshold mechanism
• Offers flexible output configuration supporting both open-drain and push-pull modes
• Ensures system stability through a defined reset delay period during power transitions

Supervisors Applications

• Microprocessor supervisor circuits requiring voltage monitoring
• Portable electronic devices needing low-power supervision
• Industrial control systems utilizing wide temperature range components

Supervisors Procurement Notes

Verify the specific suffix ZAKSZ corresponds to the required output type and packaging variant. Confirm that the fixed 2.32 V threshold aligns with the target application's voltage requirements. Ensure compatibility with the SC-70-3 footprint during PCB layout. Check for RoHS compliance documentation if environmental regulations apply. Validate that the absence of manual reset and watchdog features meets the system design specifications.

Supervisors Selection Notes

Select this component when a compact supervisory solution is needed for voltages up to 5.5 V. The fixed threshold eliminates the need for external resistor networks, simplifying design. Consider the dual output option if push-pull drive capability is preferred over open-drain. The wide temperature range makes it suitable for harsh environments. Evaluate the low quiescent current benefit for battery-operated applications.
