• Reset Timeout Period: 140ms (typical)
• Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

The TC1270ASVRCTR has a total of 5 pins:

1. VCC: Power supply input
2. GND: Ground reference
3. RESET: Output reset signal
4. MR: Manual reset input
5. VTH: Threshold voltage selection pin

Functional Features

• Monitors the supply voltage continuously
• Generates a reset signal when the voltage drops below the selected threshold
• Provides manual reset capability through the MR pin
• Offers multiple threshold voltage options for flexibility

Advantages

• Low power consumption extends battery life in portable applications
• Small form factor allows for space-efficient designs
• Wide operating temperature range enables usage in various environments
• Multiple threshold voltage options cater to different system requirements

Disadvantages

• Limited to voltage monitoring and reset functionality only
• Not suitable for applications requiring complex supervisory functions

Working Principles

The TC1270ASVRCTR operates by comparing the supply voltage with the selected threshold voltage. When the supply voltage falls below the threshold, the reset signal is activated. The manual reset input allows for external control of the reset function.
