TPS3619-33DGKG4

PMIC (Power Management Integrated Circuit) is an important part of modern electronics designed to enable power management within a system. It is widely used in various applications, ranging from consumer applications such as smartphones and IoT devices to industrial applications such as power grids, data centers, and automation systems. Supervisors are one of the most important types of PMICs, used to ensure system stability and integrity while also providing features such as power on/off sequencing, system protection and fault detection, among others.

The TPS3619-33DGKG4 is a reset circuit and supervisor from Texas Instruments. It provides an accurate reset signal and adjustable RC timer with an accurate reset threshold for the monitoring and sequencing of multiple power supplies. The integrated circuit is available in an SO-28 package with a wide operating temperature range from -40°C to +125°C, and offers overvoltage sensing and fault detection. The TPS3619-33DGKG4 is suitable for a wide range of applications, including automotive and industrial applications, as well as consumer, computer, and telecom equipment.

The primary function of the TPS3619-33DGKG4 is to provide an accurate start-up sequence and maintain system stability, safety and integrity. The circuit features an adjustable reset threshold, so that it will automatically generate a reset signal when the voltage falls below a predetermined level. Therefore, if the voltage drops below a critical level, the TPS3619-33DGKG4 will send an automatic reset signal to the system, which helps to protect the system components from damage and ensure system reliability.

Moreover, the TPS3619-33DGKG4 is also equipped with an adjustable RC timer that enables it to monitor the voltage for an extended period of time and generate a reset signal at the end of the timer duration. This feature helps to prevent system lock-up and enables power-on sequencing, allowing the user to turn on multiple power supplies in the correct sequence. In addition, the TPS3619-33DGKG4 also includes a fault detection circuit to help detect erratic voltage fluctuations, overcurrent, short circuit and other abnormal operating conditions, so that the system can be shut down safely before any damage occurs.

The TPS3619-33DGKG4 is designed to be used in a wide range of applications, including automotive, consumer, industrial, computer, and telecom equipment. The circuit can help reduce the complexity of power supply design while also improving system stability and integrity and preventing system lock-up and damage. Therefore, with its wide range of features and benefits, the TPS3619-33DGKG4 is an ideal choice for any application requiring a reset circuit and supervisor.
