Performance in modern electronic products is not just measured in terms of speed, accuracy and reliability. It is also measured in terms of energy efficiency. Power Management Integrated Circuits (PMIC) are specialized integrated circuits that regulate, protect and monitor the power supply and system environment to ensure that electronic products perform at the maximum efficiency while consuming the least amount of energy. The XC6109C30ANR-G is a low leakage I²C Supervisory IC with integrated precision voltage detectors that can accurately supervise two independent supply rail voltages.

Features

The XC6109C30ANR-G is an ultra low power design that features an enhanced Power-On Reset (POR) specifically designed to enhance system reliability as well as lengthening battery life in battery powered applications. With a low quiescent current of only 1uA and an active current of only 1.1mA, the device will not hog power in battery powered applications. It also guarantees tight accuracy readings over the entire temperature range. It is also able to detect both undervoltage (UV) and overvoltage (OV) conditions, further enhancing system reliability. Another advantage of the XC6109C30ANR-G is that is has a built-in voltage detector with programmable readout levels. This allows users to program the voltage detection levels to their desired specifications. Additionally, the device is designed with an I²C interface to further extend programmability and allow easy integration into existing systems.

Applications

The XC6109C30ANR-G is mainly used in consumer and portable electronic devices as well as automotive applications. It is ideal for intelligent battery-powered systems with multiple supply rail voltages or that require voltage detection capabilities. It can also be used for system power monitoring and control in non-battery powered applications. The device can also be integrated into microcontroller applications that require the use of precision voltage detectors and the I²C interface. Some applications include smart phones and tablets, wearables, IoT(Internet of Things) devices, Digital Set Top Boxes (DTVs), Automotive infotainment and navigation systems.

Working Principle

The XC6109C30ANR-G is an I²C Supervisory IC with integrated voltage detectors. The device monitors the voltage of two independent supply rails, VDD and VDD_P. When the voltage of either rail falls outside of a programmable Operating Voltage Range (OVR), the appropriate preset warning signal is generated and a flag is set. The device utilizes an I²C interface to allow for ease of programming and also for monitoring. It contains an I²C port as well as an I²C bus disconnect/lock pin that when pulled low, disconnects the I²C interface from the system, detecting any unexpected signal conditions. The device also has an OVR bypass pin which when pulled high allows the device to ignore any OVR settings and passes the supply rail voltage through, allowing it to be monitored. The I²C port and the OVR bypass pin can be used together for finer control and monitoring.

In terms of control, the device offers an adjustable delay of up to 1ms which allows users to set up the delay time before the reset signal is activated. The reset signal can also be latching or non-latching, depending on the user\'s preferences. The device also has an external capacitor that needs to be connected in order to accurately adjust the delay time. Additionally, the device offers a low active current of only 1.1mA and is designed to meet the requirements of high capacitance loads. The XC6109C30ANR-G also features a watchdog timer which times out in 4s of programmed OVR and is used to reset the device in case a reset signal is not sent within a certain window.

Conclusion

The XC6109C30ANR-G has been developed as a low leakage I²C Supervisory IC with integrated precision voltage detectors. It is mainly used in consumer and portable electronic devices as well as automotive applications. The device is designed to accurately supervise two independent supply rail voltages and is capable of detecting both undervoltage (UV) and overvoltage (OV) conditions. It is also equipped with an I²C interface for further programmability and ease of control. The device also offers a built-in adjustable timer as well as an active current of only 1.1mA which ensures that it won\'t draw too much power in battery powered applications. Overall, the XC6109C30ANR-G is a convenient and reliable power management device that provides a reliable, low power means of monitoring and controlling system voltages.
