Functional Features

Undervoltage Detection

The TPS3306-15DGKG4 continuously monitors the input voltage and triggers a reset signal when it falls below the programmed undervoltage threshold. This feature prevents the system from operating in an unstable or unreliable state.

Overvoltage Detection

In case the input voltage exceeds the programmed overvoltage threshold, the TPS3306-15DGKG4 generates a reset signal to protect the system from potential damage caused by excessive voltage levels.

Manual Reset

The manual reset pin (MR) allows for an external reset signal to be applied, overriding the internal monitoring circuitry. This feature enables system initialization or recovery under specific conditions.

Adjustable Thresholds

The threshold inputs (TH) provide flexibility in setting the desired undervoltage and overvoltage thresholds. By adjusting these thresholds, the TPS3306-15DGKG4 can be tailored to meet the specific requirements of different electronic systems.

Advantages and Disadvantages

Advantages

• Reliable Voltage Monitoring: The TPS3306-15DGKG4 ensures stable operation by accurately detecting undervoltage and overvoltage conditions.
• Low Power Consumption: With its low quiescent current, this IC minimizes power consumption, making it suitable for battery-powered applications.
• Compact Package: The MSOP-8 package offers a small form factor, facilitating integration into space-constrained electronic systems.

Disadvantages

• Limited Voltage Range: The TPS3306-15DGKG4 operates within a voltage range of 1.5V to 6.0V, which may not be suitable for applications requiring higher or lower voltage levels.
• Single Threshold Adjustment: While the thresholds are adjustable, there is only one threshold for undervoltage and one for overvoltage, limiting the flexibility in fine-tuning voltage monitoring.

Working Principles

The TPS3306-15DGKG4 utilizes a precision voltage reference and comparator circuitry to continuously monitor the input voltage. By comparing the input voltage with the programmed thresholds, it determines whether the voltage is within the acceptable range or requires a reset signal to be generated.

When an undervoltage or overvoltage condition is detected, the TPS3306-15DGKG4 asserts the reset output pin, initiating a system reset or shutdown sequence. This ensures that the system remains within safe operating limits and prevents potential damage to sensitive components.
