DS1816-10+

Supervisors Overview

The DS1816-10+ is a supervisory circuit from the EconoReset series manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single power supply channel with a threshold voltage of 4.55V and provides an active-low reset signal via an open-drain or open-collector output. The device features a minimum reset timeout of 100ms and operates within a temperature range of -40°C to +85°C. It is housed in a surface-mount SOT-23-3 package.

Supervisors Feature Summary

• Automatically restarts microprocessors following power failure events
• Maintains reset state for approximately 150ms after power stabilizes
• Integrates precision temperature-compensated voltage reference
• Features efficient open-drain output with internal pull-up resistor

Supervisors Applications

• Microprocessor system supervision
• Power supply monitoring
• Embedded controller reset generation

Supervisors Procurement Notes

Verify the specific suffix against official documentation, as it defines the exact threshold voltage and tolerance. Confirm the manufacturer designation matches current Analog Devices or Maxim Integrated specifications. Ensure the package type aligns with the required PCB footprint. Check RoHS compliance status if environmental regulations apply to the target assembly.

Supervisors Selection Notes

Select this component when a fixed threshold voltage near 4.55V is required for system supervision. The open-drain output allows flexibility in interfacing with various logic levels. Consider the SOT-23-3 package for space-constrained designs. Verify that the 100ms minimum timeout meets the stabilization requirements of the connected processor or memory components.

Supervisors Part Context

This part belongs to the DS1816 family of simple reset circuits designed for cost-sensitive applications. It replaces discrete comparator and timer solutions, reducing bill-of-materials complexity. The EconoReset series focuses on providing essential power-fail detection without programmable interfaces or complex configuration options.
