DS1819AR-10+T&R

Supervisors Overview

The DS1819AR-10+T&R is a voltage monitor from the MicroMonitor series, manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1 V to 5.5 V and features a threshold accuracy of 10%. The device provides active high, active low, and push-pull output types with a reset delay time of 280 ms. It includes an integrated watchdog timer and lacks manual reset functionality. The component is housed in an SOT-23-5 package for surface mount installation.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Offers configurable active high, active low, and push-pull output options
• Provides power-fail detection capabilities without requiring manual reset

Supervisors Applications

• Monitoring 5V and 3.3V microprocessor systems
• Embedded controller supervision in industrial equipment
• Power management circuits requiring watchdog functionality

Supervisors Procurement Notes

Verify availability status as this part may be subject to limited supply or discontinuation. Confirm RoHS compliance details and check for alternative packages if the SOT-23-5 form factor is unavailable. Ensure the specific suffix matches design requirements before ordering.

Supervisors Selection Notes

Select this component when a combined voltage supervisor and watchdog timer are required in a compact SOT-23-5 package. Consider the 10% threshold accuracy and 280 ms reset delay against system timing constraints. Verify that the available output drive types meet the interface requirements of the monitored logic family.

Supervisors Part Context

This device belongs to the Maxim Integrated MicroMonitor family, designed for supervising critical voltage rails in embedded applications. It combines power-fail detection with watchdog timer functions to enhance system robustness. The series targets cost-sensitive designs requiring minimal external components while maintaining reliable operation across standard industrial temperature ranges.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the DS1819 series or newer Analog Devices supervisory ICs. Verify that substitute parts maintain the same SOT-23-5 footprint and output configuration options.
