DS1815-10+TR

Supervisors Overview

The DS1815-10+TR is a supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, belonging to the EconoReset series. It functions as a simple reset and power-on reset monitor designed for single-channel voltage supervision. The device utilizes a precision temperature-compensated reference and comparator circuit to detect when the monitored supply voltage (VCC) exceeds specified tolerance limits. Upon detecting an out-of-tolerance condition, it generates an internal power-fail signal that forces the reset output active. When VCC returns within tolerance, the reset signal remains active for a minimum of 100ms to ensure processor stability. It features a push-pull output configuration and operates within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Precision temperature-compensated voltage reference and detector for accurate monitoring
• Automatic microprocessor reset generation upon power failure detection
• Maintains reset signal for a fixed duration after power recovery to ensure system stability
• Push-pull output configuration with low current operation

Supervisors Applications

• Microprocessor system power supply supervision
• Battery-powered equipment voltage monitoring
• Embedded systems requiring reliable power-on reset sequences
• Industrial control units operating in varying thermal environments

Supervisors Procurement Notes

Verify the specific suffix and package variant against the official datasheet to ensure compatibility with the target design. Confirm availability status through authorized distributors as supply levels may fluctuate. Ensure the selected component meets the required RoHS compliance standards for the intended application environment.

Supervisors Selection Notes

Select this component when a cost-effective, single-channel voltage supervisor with a fixed delay is required. It is suitable for designs needing a push-pull output rather than open-drain configurations. Consider the specific threshold voltage accuracy and operating temperature range requirements before finalizing the choice.

Supervisors Part Context

This part belongs to the DS1815 family of supervisory circuits, which are widely used for basic power management tasks. The 'EconoReset' designation indicates a simplified feature set optimized for cost-sensitive applications. The series provides essential protection for digital logic and microcontrollers against unstable power conditions without complex configuration requirements.

Supervisors Replacement Considerations

Compatible substitutes include the DS1815R-10+T&R and DS1815R-20/T&R from Analog Devices/Maxim Integrated. These alternatives share similar functional characteristics and pinouts but may differ in package type or specific threshold tolerances.
