DS1811-15/T&R

Supervisors Overview

The DS1811-15/T&R is a voltage monitor circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 2.0V to 5.5V and features an active low, open-drain output. The device monitors a single input with a threshold voltage of 4.65V and provides a reset delay time of 150ms. It functions without manual reset or watchdog timer capabilities. The component is available in SOT-23-3 surface-mount packaging and supports operation temperatures from -40°C to +85°C.

Supervisors Feature Summary

• Provides power-fail detection via an open-drain output
• Includes built-in 150ms reset delay for stable power-up
• Compatible with standard 1-Wire network protocols

Supervisors Applications

• Embedded system power supervision
• Microprocessor reset circuits
• Battery-powered device monitoring

Supervisors Procurement Notes

Verify the specific suffix 'T&R' indicates tape-and-reel packaging when sourcing. Confirm the manufacturer designation as Analog Devices Inc. or Maxim Integrated to ensure authenticity. Check RoHS compliance status against current regulatory requirements for your region before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a simple voltage supervisor with a fixed threshold near 4.65V is required. Ensure the application does not need manual reset functionality or watchdog timers. Verify that the SOT-23-3 package fits the PCB layout constraints and that the operating temperature range meets environmental specifications.

Supervisors Part Context

This part belongs to the DS1811 series of EconoReset voltage monitors. These devices are designed for cost-sensitive applications requiring basic power management. The series typically offers various threshold voltages to accommodate different logic levels and supply rails common in consumer electronics and industrial control systems.

Supervisors Replacement Considerations

Check for direct substitutes within the DS1811 family offering different threshold voltages if system requirements change. Verify pinout compatibility with alternative voltage supervisors from other manufacturers before design substitution.
