APX810S-29SR-7: PMIC - Supervisors

PMICs are an important component of many electronic products. They provide a comprehensive range of features that allow intelligent power management of different components, thereby enabling efficient operation and improved device performance. The APX810S-29SR-7 is one such PMIC and it is a supervisor with a wide variety of features. It offers a wide input voltage range, low power consumption, over-voltage, under-voltage and over-temperature protection.In this article, we will discuss the application field and working principle of the APX810S-29SR-7 PMIC in detail.

Application Field

The APX810S-29SR-7 is a supervisor PMIC primarily used for portable and battery-powered applications. It is ideal for use in mobile computing, telecommunication, consumer electronics and automotive applications, where power management and safety critical features are essential. It is also used in applications where low power consumption is required. It can be used to monitor and protect the power supply system in order to ensure reliable operation.

Working principle

The APX810S-29SR-7 uses a wide input voltage range, typically between 2.0 and 5.5V, and employs a very low quiescent current (less than 1mA typically). It uses a configurable voltage detection window (typically 2.35V to 4.15V) so that it can detect voltage over or under-travel in the power supply rail and take the necessary action.It is also equipped with an over-temperature detection circuit that can alert the user when the chip temperature reaches a certain threshold. This helps in avoiding potential system failures which may be caused by thermal overload.Other features include voltage spike transient suppression, power-on reset control and an adjustable brown-out voltage threshold. The APX810S-29SR-7 is also programmable and supports different configurations including window-watchdog, delayed-reset, manual reset and soft-start.

Conclusion

In summary, the APX810S-29SR-7 is an advanced PMIC supervisor designed for portable and battery-powered applications. It is capable of detecting a wide range of input voltage levels, as well as monitoring the system temperature and detecting brown-outs, over-voltages and under-voltages. It also supports a variety of programming configurations and has a low quiescent current, allowing for an efficient power management system.
