Package: T&R/STR (Tape & Reel / Strip)

Essence: The DS1833-15+T&R/STR is a voltage supervisor IC that ensures stable operation of electronic systems by monitoring the power supply voltage and providing a reset signal when necessary.

Packaging/Quantity: The DS1833-15+T&R/STR is available in tape and reel packaging, with a specified quantity per reel.

Specifications

• Supply Voltage Range: 2.5V to 5.5V
• Reset Threshold Voltage: 1.575V
• Reset Timeout Period: 15ms
• Operating Temperature Range: -40°C to +85°C
• Output Type: Active-Low Push-Pull

Detailed Pin Configuration

The DS1833-15+T&R/STR has the following pin configuration:

1. GND: Ground connection
2. VCC: Power supply input
3. RESET: Active-low reset output
4. MR: Manual reset input

Functional Features

• Monitors the power supply voltage continuously.
• Generates a reset signal when the voltage falls below the reset threshold.
• Provides a manual reset option through the MR pin.
• Offers a fixed reset timeout period of 15ms.
• Utilizes an active-low push-pull output for the reset signal.

Advantages and Disadvantages

Advantages: - Ensures proper system initialization during power-up or brownout conditions. - Prevents erratic behavior caused by insufficient power supply voltage. - Provides a manual reset option for system control.

Disadvantages: - Fixed reset timeout period may not be suitable for all applications. - Limited operating temperature range (-40°C to +85°C).

Working Principles

The DS1833-15+T&R/STR operates by continuously monitoring the power supply voltage. When the voltage falls below the reset threshold of 1.575V, it generates an active-low reset signal. This signal can be used to reset the system and ensure proper initialization. The IC also includes a manual reset input (MR) that allows for additional control over the reset function.

Detailed Application Field Plans

The DS1833-15+T&R/STR is commonly used in various electronic systems where stable operation is critical. Some application fields include:

1. Microcontroller-based systems
2. Embedded systems
3. Industrial automation
4. Power management circuits
5. Battery-powered devices
