Detailed Pin Configuration

The TCM810LENB713 features a standard SOT-23-5 package with the following pin configuration:

1. GND (Ground)
2. MR (Manual Reset)
3. VDD (Supply Voltage)
4. RESET (Reset Output)
5. N/C (No Connection)

Functional Features

1. Voltage Monitoring: Monitors the power supply voltage continuously.
2. Reset Generation: Generates a reset signal when the voltage falls below the specified threshold.
3. Manual Reset: Provides a manual reset input for immediate system restart.
4. Power-On Reset Delay: Ensures a stable power-up sequence by delaying the reset output until the supply voltage reaches the specified level.
5. Reset Timeout: Maintains the reset signal for a specific period after the voltage rises above the threshold, preventing premature system operation during power-up.

Advantages and Disadvantages

Advantages: - Compact SOT-23-5 package allows for space-efficient integration into various electronic systems. - Wide supply voltage range enables compatibility with different power supply configurations. - Low quiescent current minimizes power consumption. - Manual reset input provides flexibility in system control.

Disadvantages: - Limited reset threshold voltage options may not suit all applications. - Fixed reset timeout period may not be adjustable for specific requirements.

Working Principles

The TCM810LENB713 operates by comparing the supply voltage against a preset threshold. When the voltage falls below the threshold, the reset output is activated, indicating a low-voltage condition. The reset signal remains active until the voltage rises above the threshold and the reset timeout period elapses. The manual reset input allows for immediate system restart, overriding the automatic reset function.

Detailed Application Field Plans

The TCM810LENB713 is widely used in various electronic systems where stable operation is critical. Some application fields include:

1. Microcontrollers: Ensures reliable startup and shutdown sequences, preventing data corruption or erratic behavior.
2. Embedded Systems: Provides voltage supervision to safeguard system integrity during power transitions.
3. Industrial Control Systems: Monitors power supply voltage to prevent malfunctions or damage to sensitive equipment.
4. Automotive Electronics: Enhances the reliability of automotive systems by monitoring voltage fluctuations and initiating appropriate actions.
5. Battery-Powered Devices: Protects battery-operated devices from undervoltage conditions, preserving battery life and preventing data loss.
