ADM1817-10ART-RL7

Supervisors Overview

The ADM1817-10ART-RL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor system power integrity. It operates within a supply voltage range up to 5.5 V and features a push-pull output configuration for reliable signal transmission. The device provides a fixed reset delay time of 250 ms to ensure stable power-up sequencing. It supports multiple threshold voltages including 2.5 V, 3 V, 3.3 V, and 5 V, with the specific '-10' suffix indicating a 10 V threshold variant in some contexts, though standard datasheets list lower thresholds; however, based on the provided source data for the ADM1817 series, it lacks manual reset and watchdog timer functions. The component is housed in an SOT-23-3 package and is rated for operation between -40 C and +105 C, consuming a typical quiescent current of 16 uA.

Supervisors Feature Summary

• Monitors single input voltage with high accuracy supervision
• Provides active low or high reset signals via push-pull output
• Ensures system stability with fixed reset delay timing
• Operates efficiently with ultra-low quiescent current consumption

Supervisors Applications

• Portable battery-powered equipment requiring low standby current
• Microprocessor and microcontroller power supply monitoring
• Smart cards and smart card interfaces
• Battery management systems

Supervisors Procurement Notes

Verify the exact threshold voltage specification against the official Analog Devices datasheet, as the '10' designation may imply a specific voltage level not explicitly detailed in the general series summary. Confirm availability status, as the related ADM1817-5ARTZ-RL7 model indicates potential discontinuation or limited supply constraints. Ensure the SOT-23-3 package footprint matches your PCB design requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a simple, low-cost supervisor with a fixed delay is required without manual reset or watchdog capabilities. Compare the 16 uA operating current against other series members if power efficiency is critical. Verify that the 250 ms reset delay aligns with your system's power-up sequence timing requirements. Consider the -40 C to +105 C temperature range suitability for your specific environmental conditions.

Supervisors Part Context
