Specifications

• Supply Voltage Range: 1.2V to 5.5V
• Threshold Voltage Options: 2.63V, 3.08V, 4.38V
• Reset Timeout Period: 140ms (typical)
• Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

The TC1271ATCVCTTR has a total of 5 pins: 1. GND: Ground connection 2. VDD: Positive supply voltage input 3. RESET: Active-low reset output 4. MR: Manual reset input 5. TH: Threshold voltage selection pin

Functional Features

• Precision Monitoring: The TC1271ATCVCTTR accurately monitors the supply voltage and ensures reliable operation.
• Reset Output: When the supply voltage drops below the selected threshold, the IC asserts an active-low reset signal.
• Manual Reset Input: The MR pin allows for manual resetting of the device, overriding the automatic reset function.
• Threshold Voltage Selection: The TH pin enables the selection of different threshold voltage options.

Advantages and Disadvantages

Advantages: - Low-power consumption - Small package size - Wide operating voltage range - Precision monitoring for reliable system operation

Disadvantages: - Limited threshold voltage options - Lack of adjustable timeout period

Working Principles

The TC1271ATCVCTTR operates by continuously monitoring the supply voltage using an internal voltage reference. When the voltage falls below the selected threshold, the IC asserts a reset signal, indicating a power failure or unstable voltage condition. The reset output remains active until the supply voltage rises above the threshold and the timeout period elapses.

Detailed Application Field Plans

The TC1271ATCVCTTR is commonly used in various applications where reliable voltage monitoring is crucial. Some potential application fields include: - Battery-powered devices - Microcontrollers and microprocessors - Industrial control systems - Automotive electronics - Power management circuits
