The TPS3620-33DGKRG4 device is a specialized PMIC, or Power Management Integrated Circuit, belonging to the Supervisors family. This device is designed to provide microcontroller reset protection and power-up sequencing. The TPS3620-33DGKRG4 utilizes proprietary technology to allow the controlling of multiple voltage rails, such as memory and a processor core, with a single, concise controller.

The application field of the TPS3620-33DGKRG4 are system-level reset protection, precise startup/shutdown sequencing, and controlled reset generation. It is a suitable choice for power engineers and designers as it provides high immunity to ESD and transient events, precise sequencing of power-up and power-down, adjustable reset threshold, and fast response time.

The working principle of the TPS3620-33DGKRG4 involves two-level reset protection, precise control over power-up/power-down sequencing, and adjustable reset threshold. There are two sub-systems in the TPS3620-33DGKRG4, one for monitoring the supply voltage, and the other for driving the primary reset output.

The monitoring sub-system of the TPS3620-33DGKRG4 consists of a voltage monitor, an analog-to-digital converter, and a 3-bit reference voltage. When the supply voltage is above the reference voltage, the voltage monitor continuously samples the supply voltage and sends a signal to the controller when the voltage exceeds the preset reset threshold. The controller then activates the reset output.

The second sub-system of the TPS3620-33DGKRG4 consists of a driver and a voltage regulator. The driver enables the controller to drive the reset output. The voltage regulator is used to maintain a constant reference voltage to ensure accuracy.

The TPS3620-33DGKRG4 is capable of providing system stability, precise startup/shutdown sequencing, and immunity against ESD and transient events. It is designed to be user-friendly, ensuring easy and efficient configuration of the reset threshold and power-up/power-down sequencing. Furthermore, the reset response time of the TPS3620-33DGKRG4 is fast and stable, providing complete assurance of system stability.

In conclusion, the TPS3620-33DGKRG4 is a versatile PMIC belonging to the Supervisors family. The device is designed to provide reset protection, precise power-up/power-down sequencing, adjustable reset threshold, and fast reset response time. It is a suitable choice for power engineers and designers, as it ensures system level stability and protection from ESD and transient events.
