| | --| |-- |____| | | |__| ```

Pin 1: VDD - Supply voltage input\ Pin 2: GND - Ground\ Pin 3: RESET - Active low reset output

Functional Features

• Voltage monitoring: The TC1272-15ENBTR continuously monitors the supply voltage and provides a reset signal when it falls below the threshold voltage.
• Power-on reset: It ensures that the system is properly initialized by generating a reset signal during power-up.
• Low quiescent current: The device consumes minimal current, making it suitable for battery-powered applications.
• Push-pull output: The active low push-pull output provides a strong and reliable reset signal to the connected circuitry.

Advantages and Disadvantages

Advantages

• Accurate voltage monitoring
• Low power consumption
• Small package size
• Wide operating temperature range

Disadvantages

• Fixed threshold voltage (1.5V)
• Limited output options

Working Principles

The TC1272-15ENBTR operates by comparing the supply voltage with the fixed threshold voltage. When the supply voltage drops below the threshold, the reset output is activated, signaling a power failure or an unstable voltage condition. This allows the connected circuitry to take appropriate actions to ensure proper operation or safe shutdown.
