XC6121F530ER-G

The XC6121F530ER-G is a PMIC (Power Management Integrated Circuit) supervisor designed as a voltage monitoring device. It provides quick, reliable and accurate power-source protection and management for a wide variety of different applications. This article will discuss the XC6121F530ER-G application field and working principle in detail.

Application Fields:

The XC6121F530ER-G supervisor is perfect for a wide range of applications where smart, quick and accurate power management is required. These applications range from general power monitoring and protecting for automotive, consumer cycling applications such as server, storage and IoT, to industrial, medical and precision instrumentation. In addition, the device is also a great choice for managing power in battery-operated products such as drones, drones and robotics.

The device can be easily integrated into existing systems due to its small size, low power consumption and wide temperature range (-40°C to +125°C). Furthermore, the design of the device reduces the need for over-voltage and current protection components. The safety of the device is further increased thanks to its multiple protection features, such as over-current, over-voltage, short-circuit and thermal protection.

Working Principle:

The XC6121F530ER-G supervisor monitors two power inputs, VDD1 and VDD2, and a reset signal from the host board. To protect the VDD1 input, a 3-channel OCP (Over Current Prevention) circuit is provided for the “Three Energy Control SIP”. The device also has two over-voltage protection channels, one for each input, and supports switching-mode power supply systems. It also includes an internal timer circuit for reset signal output and a temperature monitoring circuit.

When a power over-voltage or thermal threshold is detected, the device automatically shuts down the power source to ensure safety. When a power over-current or short circuit is detected, the device immediately triggers the over-current protection circuit to cut off the power supply. The device also provides an adjustable reset signal timing circuit to match the host board requirements. The reset signal output can be set with a 0.9V threshold voltage, and the device can generate a reset signal with a duration of 0.5ms to 500ms.

In addition, the XC6121F530ER-G also features a precision voltage monitor circuit that detects the voltage difference between the two power sources. This feature enables the device to accurately perform low side and high side monitoring for power applications. Furthermore, the device supports several I2C/SMBus protocols, allowing for easy communication between devices.

Overall, the XC6121F530ER-G is a power management integrated circuit supervisor perfectly adapted for a wide range of applications where reliable and efficient power management is required. It offers several protection features to ensure safety and can be easily integrated into existing systems. Furthermore, its communication protocol and monitor circuit allows for quick and accurate power monitoring and protection.
