Functional Features

Voltage Supervisor

TLC7705IPG4 acts as a voltage supervisor by continuously monitoring the supply voltage. It generates a reset signal when the voltage falls below a user-defined threshold, ensuring proper system operation.

Watchdog Timer

The built-in watchdog timer in TLC7705IPG4 helps prevent system lock-ups. It requires periodic activation from the microcontroller, failing which it generates a reset signal to restart the system.

Adjustable Threshold

The threshold voltage can be adjusted using an external resistor divider network, allowing flexibility in setting the desired voltage level for triggering the reset signal.

Advantages and Disadvantages

Advantages

• Wide operating voltage range enables compatibility with various power supply systems.
• Small package size makes it suitable for space-constrained applications.
• Adjustable threshold voltage provides customization options.
• Low supply current consumption helps conserve power.

Disadvantages

• Lack of built-in hysteresis may lead to potential noise-related issues.
• Limited timeout period range may not cater to certain specific application requirements.

Working Principles

TLC7705IPG4 operates by continuously monitoring the supply voltage through the TH pin. When the voltage falls below the user-defined threshold, the RESET pin is driven low, indicating a reset condition. The watchdog timer requires periodic activation from the microcontroller to prevent system lock-ups. Failure to activate the watchdog timer within the specified timeout period results in a reset signal being generated.

Detailed Application Field Plans

TLC7705IPG4 finds applications in various electronic systems, including but not limited to: - Automotive electronics - Industrial control systems - Power management units - Battery-powered devices - Home automation systems
