PMIC - Supervisors play an important role in the management of crucial electrical components on a circuit, ensuring their safe and reliable operation. The TPS3306-15DGKG4 is a PMIC-Supervisor that offers system-level protection from overvoltage, reverse voltage, undervoltage, and power failure. In this article, the application field and working principle of the TPS3306-15DGKG4 will be outlined.

Application Field:

The TPS3306-15DGKG4 offers protection for a variety of systems, including embedded systems, switching power supplies, industrial automation systems, and motor control systems. This PMIC-Supervisor provides overvoltage protection (OVP) of up to 15V, reverse voltage protection (RVP) of up to 15V, and undervoltage protection (UVP) of up to 4.08V. Additionally, the TPS3306-15DGKG4 offers power-failure protection (PFP), making it well-suited for systems with time-sensitive components.

The TPS3306-15DGKG4 is equipped with two voltage levels and two delay times, allowing users to adjust the protection threshold. Additionally, the device provides easy monitoring and adjustment of system parameters. This is achieved through the integrated watchdog timer and adjustable level reset value, which reset the system if needed. Furthermore, the TPS3306-15DGKG4 is a two-output device, meaning two protected systems can be monitored and adjusted simultaneously.

Working Principle:

The TPS3306-15DGKG4 employs a dedicated integrated circuit (IC) that implements the main protection functions. The IC is connected to the power supply rail and to the circuit\'s protected component. The IC monitors the supply voltage (Vin) and can detect any voltage disturbances or over-/under-voltage events. When such an event occurs, the IC will activate the reset function, which will switch off or reset the protected component.

The TPS3306-15DGKG4 also features a watchdog timer that monitors the system. This allows the Supervisor to detect faults in the system, such as an overload, short-circuit, or component failure. If the fault is detected, the Supervisor will reset the system and its components. The user-adjustable voltage levels and delay times allow the user to customize the protection thresholds.

In addition, the TPS3306-15DGKG4 offers protection against power failure. This feature will detect when the supply voltage drops below a programmed level, resetting the system and its components. The device also prevents false triggering during sustained power-failure events, ensuring reliable system protection.

Conclusion:

The TPS3306-15DGKG4 is a PMIC-Supervisor that offers robust system-level protection from overvoltage, reverse voltage, undervoltage, and power failure. This Supervisor is well-suited for embedded systems, switching power supplies, industrial automation systems, and motor control systems, due to its adjustability and wide voltage range. Additionally, the integrated watchdog timer and adjustable level reset value allow for easy monitoring and system adjustment. Finally, the TPS3306-15DGKG4 provides reliable power-failure protection, ensuring high system reliability.
