PMIC (Power Management Integrated Circuit) supervisors provide precision monitoring and control of voltage, current, and temperature. They are highly integrated and cost effective solutions for power management applications in computing, communications and consumer electronics markets. The X40411V8I-AT1 is a fully integrated PMIC supervisor developed for automotive applications with integrated high-precision voltage monitoring, high-performance current monitoring and temperature control, and hardware watchdog timer.

The operating principle behind the X40411V8I-AT1 is straightforward and easy to understand. The power supply is monitored via integrated voltage monitors and a software distributed voltage supervision chain and a high-precision temperature sensor. Once the situation demands corrective action, a hardware timer initiates an interrupt which points software to objects of interest. The current monitoring device in the module is an analog-to-digital converter (ADC) which converts the analog signal into a digital form. This complex feedback network then can trigger a variety of events such as current limit, voltage foldback and temperature control.

The X40411V8I-AT1 can be used in a number of automotive applications such as automotive audio systems, infotainment systems and advanced driver-assistance systems (ADAS). With its wide range of operating temperature (-40°C to +125°C) and low operating current, it is a low power, low cost option for automotive power management applications. The module also provides a number of advanced features, such as power-on reset and brown-out reset, auto-start monitoring, wake-up control and dual preset supply under-voltage detection.

The X40411V8I-AT1 provides comprehensive protection against over-voltage and over-current events. It monitors the supply voltage and will generate a reset signal if the voltage exceeds programmed limits. Similarly, the temperature monitor will generate an interrupt if temperatures exceed programmed levels. The software distributed voltage supervision chain is used to provide further protection against transient and step conditions. It also provides over-temperature protection and auto-adjusts reference voltage when input voltage is changing.

The X40411V8I-AT1 also provides a watchdog timer which is triggered when the system fails to communicate or update the timer count within a given duration. This helps to protect the system from hang or any other irregular operation. Finally, it offers a Brownout reset feature which pulls the output voltage below a programmed level in order to lower power consumption during certain events such as theft or disabling of the system for any reason.

In summary, the X40411V8I-AT1 is a highly integrated PMIC supervisor which provides precision monitoring and control of voltage, current, and temperature. It provides comprehensive protection which is essential for automotive applications due to the harsh environment. The device is cost effective and provides a range of features making it ideal for power management applications in automotive, computing, communications and consumer electronics markets.
