Essence

The essence of the TCM809ZVLB713 is its ability to monitor and control the power supply voltage, ensuring stable operation of electronic devices.

Packaging/Quantity

The TCM809ZVLB713 is typically sold in reels containing a quantity of 3000 units per reel.

Specifications

• Supply Voltage Range: 1.6V to 5.5V
• Threshold Voltage: 2.93V (fixed)
• Operating Temperature Range: -40°C to +85°C
• Output Type: Active Low
• Reset Timeout Period: 140ms (typical)

Detailed Pin Configuration

The TCM809ZVLB713 has three pins:

1. VDD: Power supply input pin.
2. GND: Ground reference pin.
3. RESET: Active low reset output pin.

Functional Features

• Monitors the power supply voltage and generates a reset signal when the voltage falls below the threshold.
• Provides a stable reset output during power-up, power-down, and brownout conditions.
• Low-power consumption.
• Small package size for space-constrained applications.

Advantages and Disadvantages

Advantages

• Wide supply voltage range allows compatibility with various electronic devices.
• Fixed threshold voltage ensures consistent performance.
• Active low reset output simplifies integration with microprocessors.
• Low-power consumption helps to extend battery life in portable devices.

Disadvantages

• The fixed threshold voltage may not be suitable for all applications requiring different voltage levels.
• Limited timeout period for the reset signal may not be sufficient for certain system recovery processes.

Working Principles

The TCM809ZVLB713 operates by continuously monitoring the power supply voltage. When the voltage falls below the fixed threshold of 2.93V, it generates an active low reset signal. This signal remains active until the voltage rises above the threshold again. The device ensures stable operation during power-up, power-down, and brownout conditions.

Detailed Application Field Plans

The TCM809ZVLB713 finds application in a wide range of electronic devices, including but not limited to:

1. Microcontrollers and microprocessors
2. Embedded systems
3. Portable devices
4. Industrial control systems
5. Communication equipment
6. Automotive electronics
