Essence

This component serves as a reset supervisor, ensuring proper system initialization and preventing erratic behavior during power-up or brownout conditions.

Packaging/Quantity

The DS1811R-10+T&R is typically packaged in reels, with each reel containing a specific quantity of components. The exact quantity may vary depending on the manufacturer's specifications.

Specifications

• Supply Voltage: 2.7V to 5.5V
• Reset Threshold Voltage: 4.63V
• Reset Timeout Period: 10ms
• Operating Temperature Range: -40°C to +85°C
• Output Type: Active-Low Push-Pull

Detailed Pin Configuration

The DS1811R-10+T&R has the following pin configuration:

1. GND (Ground)
2. RESET (Reset Output)
3. VCC (Supply Voltage)

Functional Features

• Power-On Reset: The DS1811R-10+T&R generates a reset signal when the supply voltage rises above the reset threshold, ensuring proper system initialization.
• Brownout Detection: It monitors the supply voltage and asserts the reset signal if it falls below the reset threshold, preventing erratic behavior during low voltage conditions.
• Reset Timeout: The component keeps the reset signal asserted for a specific period (10ms) after the supply voltage rises above the reset threshold, allowing the system to stabilize before normal operation.

Advantages and Disadvantages

Advantages

• High reliability and accuracy ensure proper system initialization.
• Compact size enables integration into small electronic devices.
• Wide operating temperature range ensures functionality in diverse environments.

Disadvantages

• Limited reset timeout period may not be suitable for systems requiring longer stabilization time.
• Active-low push-pull output type may not be compatible with all system architectures.

Working Principles

The DS1811R-10+T&R operates by continuously monitoring the supply voltage. When the voltage rises above the reset threshold, it generates a reset signal, which remains asserted for the specified timeout period. If the voltage falls below the reset threshold, the reset signal is immediately asserted again, ensuring system stability during brownout conditions.

Detailed Application Field Plans

The DS1811R-10+T&R finds applications in various fields, including but not limited to: - Consumer electronics - Industrial automation - Automotive systems - Medical devices - Telecommunications
