XC6121E542ER-G

XC6121E542ER-G is a high-performance Power Management IC (PMIC) with Supervisory circuit. It is designed to provide robust, reliable and efficient power management solutions for IoT and embedded system applications. It provides a fully certified, safe-and-smooth power system solution by applying a patented advanced monitoring technology.

The XC6121E542ER-G is a very versatile PMIC suitable for many applications. It is featured with several dedicated regulators for independent power control, protection, and monitoring. It provides voltage monitoring from 1.2V to 4.5V, up to 1A current, over-current and over-temperature protection, as well as protective circuit monitoring. With the highest integration and optimized setup, the XC6121E542ER-G reduces component count, component sizes, board depth and even time to market.

In terms of Supervisory circuit, the XC6121E542ER-G can detect potential faults in the system, e.g. short circuit, transformer winding fault, or supply loss. It can also provide protection against reverse current, under-voltage and over-current conditions. The device comes with a user-configurable input/output threshold and over-current level to ensure system safety.

XC6121E542ER-G comes with an advanced monitoring technology, which includes an integrated analog comparator and an external accelerometer. The internal analog comparator monitors system parameters such as power supply voltage, load current, and temperature, while the external accelerometer detects potential mechanical defects in the system.

The XC6121E542ER-G can also provide additional features such as wake functions (Wake-on-Lan, Wake-on-Mouse/Keyboard, etc.), which enable the IC to go into sleep or power saving modes when its input signals are low. It can automatically detect input signals and wake up the device, allowing the user to save power and space.

XC6121E542ER-G is suitable for industrial, consumer, and automotive applications. It is available in an SO-8 package for an easy PCB mounting, and it is pin-compatible with other XC6121E542ER-G devices. Finally, the device comes with a separate logic-level power supply pin which allows the device to be powered by a direct current source.
