Essence
The essence of this product lies in its ability to provide reliable voltage monitoring and reset generation functionality in electronic systems.
Packaging/Quantity
The TCM809SENB713 is usually packaged in reels or tubes, with quantities varying depending on the supplier.
Specifications
- Supply Voltage Range: 1.6V to 5.5V
- Reset Threshold Voltage Options: 2.63V, 2.93V, 3.08V, 4.38V, 4.63V
- Reset Timeout Period: 140ms (typical)
- Quiescent Current: 1.0µA (typical)

Detailed Pin Configuration
The TCM809SENB713 has three pins:
- VDD: Power supply input pin.
- GND: Ground reference pin.
- RESET: Output pin that provides the reset signal.
Functional Features
- Voltage Monitoring: The TCM809SENB713 continuously monitors the supply voltage and asserts the RESET pin when it drops below the specified threshold.
- Reset Generation: When the supply voltage falls below the threshold, the RESET pin is driven low, indicating a reset condition to the connected microcontroller or system.
- Reset Timeout: The IC includes an internal timer that keeps the RESET pin low for a specific period (140ms typical) after the supply voltage rises above the threshold. This prevents premature system restarts due to temporary voltage fluctuations.
Advantages and Disadvantages
Advantages
- Low power consumption enables energy-efficient operation.
- Wide operating temperature range ensures reliability in various environments.
- Small package size allows for space-saving integration.
- Multiple reset threshold options provide flexibility for different applications.
Disadvantages
- Limited reset timeout period may not be suitable for all system requirements.
- Availability of alternative models with additional features may be limited.
Working Principles
The TCM809SENB713 operates by comparing the supply voltage with the preset threshold voltage. When the supply voltage drops below the threshold, the internal circuitry triggers the RESET pin, indicating a reset condition. Once the supply voltage rises above the threshold and remains stable for the reset timeout period, the RESET pin returns to its inactive state.
Detailed Application Field Plans
The TCM809SENB713 finds applications in various electronic systems, including but not limited to: - Microcontrollers and microprocessors - Embedded systems - Industrial control systems - Battery-powered devices - Automotive electronics
Detailed and Complete Alternative Models
While the TCM809SENB713 offers reliable voltage monitoring and reset generation capabilities, there are alternative models available in the market that cater to specific application requirements. Some notable alternatives include: - TPS3808G01: Offers adjustable reset threshold voltage and longer reset timeout period. - MAX809: Provides additional features such as manual reset input and watchdog timer functionality. - ADM803: Includes a power-on reset delay feature and adjustable reset threshold voltage.
