DS1815-10+T&R

Supervisors Overview

The DS1815-10+T&R is a single-channel voltage supervisor from the EconoReset series, manufactured by Analog Devices Inc./Maxim Integrated. It provides system reset functionality for microprocessors and logic circuits. The device features a fixed threshold voltage of 4.35V with a 10% accuracy tolerance. It supports a supply voltage range from 1.2V to 5.5V and operates within a temperature range of -40°C to +85°C. The component utilizes a push-pull/totem pole output configuration and offers a minimum reset timeout of 100ms. It is available in surface-mount packages including SOT-23-3 and TO-92-3.

Supervisors Feature Summary

• Provides reliable system reset signals for digital circuits under low-voltage conditions
• Features non-volatile memory to retain user-defined settings without external components
• Supports flexible output configurations through programmable control registers

Supervisors Applications

• Microprocessor system supervision
• Battery-powered device monitoring
• Logic circuit protection

Supervisors Procurement Notes

Verify the specific package variant (SOT-23-3 or TO-92-3) required for your design, as the base part number may correspond to different physical footprints depending on the suffix. Confirm availability status directly with authorized distributors, as lead times and stock levels fluctuate. Ensure the selected revision matches the datasheet specifications for threshold voltage and operating temperature range before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a simple, cost-effective reset solution is needed for systems operating between 1.2V and 5.5V. The fixed 4.35V threshold makes it suitable for standard 5V logic families. Consider the programmable nature if custom reset delays or output polarities are required. Evaluate thermal requirements against the -40°C to +85°C industrial grade specification. Compare pin-out compatibility with existing PCB layouts if replacing older supervisor ICs.

Supervisors Part Context

This part belongs to the Maxim Integrated EconoReset family, designed for low-cost voltage monitoring applications. It complements other supervisors like the DS1812 and DS1819 by offering programmable features alongside fixed thresholds. The series targets embedded systems requiring robust power management without complex external circuitry.

Supervisors Replacement Considerations

Direct substitutes include the DS1812R-10+T&R for similar SOT-23-3 packaging with comparable threshold characteristics. For through-hole applications, the DS1815-20/T&R serves as a functional equivalent in TO-92-3 packages. Verify pin compatibility and threshold voltage alignment when cross-referencing these alternatives.
