PMICs, or power management integrated circuits, are an essential component of any electronic device. The TPS3808G25DBVTG4 is a PMIC supervisor, which is an integrated circuit designed for use in a variety of power applications that require high current or voltage management. It is an excellent choice for microprocessor-based systems, including embedded systems, computers, automotive and industrial systems. In this article, we will discuss the TPS3808G25DBVTG4 application field and working principle.

TPS3808G25DBVTG4 Application Field

The TPS3808G25DBVTG4 PMIC supervisor is a low-power supervisor that can be used in a wide variety of applications. It has two main functions: reset and power-on sequencing. It can be used to monitor power-on reset (POR) conditions, as well as detecting overvoltage (OV) or undervoltage (UV) events. In addition, it can be used to set and reset power-up and power-down defaults. It is designed to provide very stable and reliable performance in any application.

The TPS3808G25DBVTG4 is suitable for a variety of power management applications, including automotive systems, consumer electronics, computers, and mobile device charging. It is designed to be used with 5V and 12V power rails and can be used to prevent false resets by monitoring MCP timing. It is highly accurate, with no hysteresis. It provides systemic fault detection and can detect short circuits, open circuits, and overvoltage conditions.

Working Principle

The TPS3808G25DBVTG4 has two main functions: reset and power-on sequencing. When the device is powered on, the reset pin is initially set low to indicate that a reset has occurred. This pin is then released and the power-on sequencing begins. The internal logic monitors the VDD and VSS power supply rails, as well as the supplier’s power sequencing requirements. If the voltage rails reach their respective thresholds without issue, the power-on sequencing is complete and the device is ready for operation.

For the reset function, the device is designed to precisely monitor the voltage rails and detect any overvoltage (OV) or undervoltage (UV) events. When an OV or UV event is detected, the reset pin will be triggered and the device will reset. This provides protection to the power rails in the event of a voltage event. It also ensures that the power-on sequence is properly followed and that the voltage rails remain at their proper levels.

The device also features a watchdog timer, which ensures that system activity does not go unchecked. This timer can be adjusted to the desired period to reduce false resets and ensure reliable operation. The device is designed to reduce system noise and interference, allowing for more reliable performance.
