DS1810-10+

Supervisors Overview

The DS1810-10+ is a supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It provides reset functionality for microprocessors and logic circuits with a fixed output delay of 100 ms. The device monitors the VCC supply voltage and asserts a reset signal when the voltage drops below a specific threshold. It operates within a supply voltage range of 2.0V to 6.0V. The component features a push-pull active-low output and includes an open-drain manual reset input. It is designed to ensure reliable system startup and recovery from power failures in embedded applications.

Supervisors Feature Summary

• Provides precise voltage monitoring with a fixed 100 ms output delay
• Features an active-low push-pull reset output for direct interface with digital logic
• Includes an open-drain manual reset input for external control
• Operates reliably across a wide supply voltage range without requiring external components

Supervisors Applications

• Microprocessor reset circuits in embedded systems
• Battery-powered devices requiring low-voltage detection
• Portable electronics needing reliable power-fail recovery
• Industrial control systems with strict reset timing requirements

Supervisors Procurement Notes

Verify the exact suffix (+) indicates lead-free compliance per RoHS standards. Confirm the package type matches your PCB footprint, typically SOT-23 or similar small outlines. Check the datasheet for the specific voltage threshold variant, as the base model may have different trip points. Ensure the operating temperature range meets your application's environmental specifications. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Supervisors Selection Notes

Select this component when a fixed 100 ms delay is required for system stability. Consider the supply voltage range to ensure compatibility with your system's power rails. Evaluate the need for a manual reset input if external user intervention is necessary. Compare the quiescent current against battery life requirements for portable designs. Verify that the output drive capability meets the load requirements of the connected microprocessor or logic gate.

Supervisors Part Context

The DS1810 series belongs to Maxim Integrated's line of supervisory circuits designed for cost-sensitive applications. These devices are commonly used in consumer electronics and industrial equipment where space is limited. The + suffix denotes lead-free packaging compliant with international environmental regulations. This specific model offers a balance of performance and simplicity, making it suitable for basic reset functions without complex configuration.
