Functional Features

1. Voltage Monitoring: The TLE2301INEE4 continuously monitors the voltage level at the IN pin and compares it with the threshold voltage set by the TH pin.
2. Threshold Adjustment: The TH pin allows users to adjust the threshold voltage within a specified range, enabling customization for different applications.
3. Watchdog Timer: This IC incorporates a watchdog timer that can be used to monitor system activity. If the WDI pin is not toggled within the timeout period, the RST pin is activated, triggering a system reset.
4. Low Power Consumption: With a quiescent current of only 10µA, the TLE2301INEE4 minimizes power consumption, making it suitable for battery-powered devices.

Advantages and Disadvantages

Advantages

• Wide supply voltage range enables compatibility with various systems.
• Adjustable threshold voltage provides flexibility for different voltage monitoring requirements.
• Built-in watchdog timer enhances system reliability.
• Low power consumption prolongs battery life in portable applications.

Disadvantages

• Limited number of pins may restrict the integration of additional features.
• Lack of built-in hysteresis circuitry may require external components for noise immunity.

Working Principles

The TLE2301INEE4 operates by comparing the voltage at the IN pin with the threshold voltage set by the TH pin. If the input voltage falls below the threshold, the RST pin is activated, indicating a voltage fault. Additionally, the watchdog timer monitors the activity at the WDI pin. If no toggling is detected within the timeout period, the RST pin is triggered, initiating a system reset.
