DS1819AR-5+T&R

Supervisors Overview

The DS1819AR-5+T&R is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1 V to 5.5 V and monitors a single input channel. The device features active high and active low push-pull outputs with a reset delay time of 280 ms. It includes an integrated watchdog timer and lacks manual reset functionality. The component is housed in a SOT-23-5 surface-mount package and functions reliably across an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system fault recovery
• Provides dual active high and active low push-pull output configurations
• Supports power-fail detection capabilities

Supervisors Applications

• Embedded system power supervision
• Microcontroller reset management
• Portable electronic device protection

Supervisors Procurement Notes

Verify the exact suffix designation against official manufacturer documentation, as variations exist within the DS1819 family. Confirm RoHS compliance status and current lifecycle stage through authorized distributors. Ensure the specific ordering code matches the required pinout and electrical characteristics for your design implementation.

Supervisors Selection Notes

Select this component when a single-channel voltage monitor with both over-voltage and under-voltage thresholds is required. The inclusion of a watchdog timer distinguishes it from basic reset controllers. Verify that the SOT-23-5 package fits the board layout constraints and that the 1 V minimum operating voltage aligns with the system power rails.

Supervisors Part Context

This part belongs to the Maxim Integrated MicroMonitor series, designed for compact power management applications. The DS1819 family provides essential supervisory functions in small form factors. Analog Devices acquired Maxim Integrated, consolidating these product lines under the parent company brand structure.

Supervisors Replacement Considerations

Consult official substitution guides for compatible parts within the DS1819 series or equivalent supervisory circuits from other manufacturers. Verify pin compatibility and electrical parameter alignment before replacing.
