PMIC - Supervisors integrate protection and power-on reset circuits, which are essential components in many power management systems. The TPS3306-25DG4 is a low-cost supervisor available in a 4 mm x 4 mm QFN package. This supervisor provides protection against short circuits, over-current, and over-voltage as well as a pushbutton power-on reset output. The device also features ±1% accuracy for its voltage threshold. This makes the TPS3306-25DG4 an ideal choice for many power management solutions.

The TPS3306-25DG4 is designed to support a wide range of voltage levels from 2.8 V to 5.5 V. It can monitor any voltage between 0.8 V and 3.4 V and provide a reset signal when the monitored voltage drops below its threshold. It features an adjustable reset timeout period of 40 ms to 140 ms. The TPS3306-25DG4 also offers very low standby current of < 1 µA in normal operation and a low active current of 25 µA in power-on reset mode.

The working principle of the TPS3306-25DG4 is simple. It contains both a voltage supervisor and a power-on reset circuit. The voltage supervisor is responsible for monitoring the input voltage and issuing a reset signal when the voltage falls below the threshold. The power-on reset circuit is responsible for providing a reset signal when the power is initially applied. This reset signal is then used to reset any system circuitry on power-up.

The TPS3306-25DG4 has many applications in various systems, such as telecommunications, networking, and automotive. In telecommunications, the supervisor can be used to monitor the voltage levels of mobile handsets and issue a reset signal if the voltage drops below a certain threshold. In networking, the supervisor can be used to monitor the voltage levels of network switches and routers and provide a reset signal if the voltage falls below the preset threshold. In automotive, the supervisor can be used to monitor the voltage levels of vehicle control systems and provide protection against voltage faults.

The TPS3306-25DG4 is a convenient and low-cost way to meet the safety and protection needs of many different types of power systems. The low standby current, wide voltage range, and adjustable reset timeout period make the TPS3306-25DG4 an ideal choice for many power management solutions. It is capable of providing protection against short circuits, over-current, over-voltage, and power-on reset. All of these features come in a compact 4 mm x 4 mm QFN package and make the TPS3306-25DG4 a great choice for many power systems.
