TPS3600D20PWG4

PMIC (Power Management Integrated Circuit) supervisors are integrated circuits that help manage the power system of any device by monitoring and adjusting the input voltage and current levels. The TPS3600D20PWG4 is a PMIC supervisor designed for applications ranging from low power to high power systems. It can monitor, reset and protect from under-voltage conditions. In this article, we will discuss the application field and working principle of the TPS3600D20PWG4 supervisor.

The TPS3600D20PWG4 supervisor is suitable for various application fields, including portable electronic devices, automotive electronics, electronic games, alarm and industrial control systems, and automated test equipment (ATE). It supports 5V, 3V and 1.8V input voltages, and is capable of providing a reset signal when the power supply voltage exceeds or falls below the user-defined trip points. The TPS3600D20PWG4 supervisor also supports three types of active-low reset output pin configurations: open collector, CLR pin and push-pull.

The working principle of the TPS3600D20PWG4 supervisor is relatively simple. The integrated circuit features an on-chip reset comparator which compares the input power supply voltage with the user-defined trip points. When the power supply voltage is above the user-defined trip points, the reset comparator will generate a reset signal which can then be sent to other components in the system. This reset signal can then be used to reset the system or to adjust the voltages and current levels of the system.

The TPS3600D20PWG4 supervisor also supports a sleep mode feature. In this mode, the supervisor will go into a low-power state when the power supply voltage is below the user-defined trip points. This feature can be used to reduce the power consumption of the system and can also help reduce system noise. When the VCC voltage rises above the user-defined trip points, the supervisor will automatically wake up and resume monitoring and resetting the system.

The TPS3600D20PWG4 supervisor also supports a watchdog timer feature. This feature allows the supervisor to monitor the system for any abnormal behavior, such as processor stalls, deadlocks and system lock-outs. If such abnormal behavior is detected, the supervisor will generate a reset signal to reset the system and return it to a normal state. The watchdog timer feature can be used to ensure the system’s reliability and stability.

In conclusion, the TPS3600D20PWG4 is a PMIC supervisor which offers various features to help manage the system power. It can monitor voltage levels, reset the system and protect against under-voltage conditions. The supervisor also supports a sleep mode and a watchdog timer feature. This makes it suitable for a wide range of applications, ranging from low power to high power systems.
