Detailed Pin Configuration

The DS1813-10+ features a standard three-pin configuration: 1. GND: Ground connection 2. VCC: Positive supply voltage input 3. RESET: Active-low reset output

Functional Features

• Monitors the power supply voltage and asserts a reset signal when it falls below a specified threshold.
• Provides a stable reset output during power-up, power-down, and brownout conditions.
• Offers a manual reset input for external system reset control.
• Low quiescent current makes it suitable for battery-powered applications.

Advantages and Disadvantages

Advantages: - High precision voltage monitoring - Low power consumption - Wide operating voltage range - Small package size for space-constrained designs

Disadvantages: - Limited threshold voltage options - No adjustable threshold voltage

Working Principles

The DS1813-10+ operates by comparing the supply voltage with a fixed threshold voltage. When the supply voltage drops below the threshold, the reset output is asserted, indicating a power failure or unstable voltage condition. The reset output remains active until the supply voltage rises above the threshold and stabilizes.

Detailed Application Field Plans

The DS1813-10+ is commonly used in various applications where reliable voltage monitoring is crucial. Some typical application fields include: 1. Microcontroller-based systems 2. Embedded systems 3. Industrial control systems 4. Power management circuits 5. Battery-powered devices
