PMIC, otherwise known as power management integrated circuits, are essential components in modern telecommunications and consumer electronics. They act as supervisors that perform critical functions such as supporting high data rate communication protocols and providing energy management solutions. One such power management solution is the TPS3824-30DBVTG4, a low quiescent current precision reset supervisor with push button reset (PBR) feature.

The TPS3824-30DBVTG4 is designed to provide early warning of system failure via a manual reset input (PB) and a programmable reset output (RESET) for use in a variety of high speed data rate applications. It also provides a power-on reset (POR) output in order to sequence other critical components in the system. The push button reset feature eliminates the need for a permanent reset switch, enabling handheld or custom devices to be reset with a single button press. The integrated POR circuit ensures a proper system start-up, even after initial power-up power spikes.

The TPS3824-30DBVTG4 is a highly integrated, low-power supervisor with wide-operating voltage range, which can be used in both high- and low-voltage systems. It is also optimized to consume lower standby power compared to similar supervisors and is available in small SOT-23 and MSOP packages. The device also has a built-in reset signal hysteresis feature which allows the device to reset below the de-assertion signal delay without generating false reset signals.

The TPS3824-30DBVTG4 can be used in a variety of applications, including wireless communication systems, consumer electronics, industrial automation and home automation systems. For example, it can be used in wireless consumer products to ensure the device receives the proper reset, as well as in industrial systems to guarantee a consistent reset under varying temperature and power supply conditions. In addition, the device can be used in low-voltage systems for sequential device start-up, providing a power-on reset output for each device in the system.

The TPS3824-30DBVTG4 employs a wide-voltage precision reset threshold and hysteresis circuit in order to provide accurate and reliable system resetting. Under normal operation, the device monitors the power and logic signal voltages and keeps the RESETb output low. When either the logic signal or the power supply voltage drops below the reset threshold, the RESETb output is asserted until both the logic signal and the power supply voltage again exceed the reset threshold plus the hysteresis voltage.

Overall, the TPS3824-30DBVTG4 is a very powerful and reliable reset supervisor with a wide range of applications. Its ability to provide a reset signal to systems during power up and power down states makes it an ideal choice for a variety of applications. Furthermore, its low quiescent current and small-size packages make it a great fit for use in handheld and consumer electronics products as well as industrial and home automation systems.
