Supervisors are typically integrated circuits used for monitoring power and resetting the main system if a predetermined operating condition goes out of limit. The XC6122E539ER-G is an example of such supervisor IC. It is an LDO Voltage Detector that features low current consumption, low standby current, and high precision voltage detection, making it suitable for a wide range of applications.

The XC6122E539ER-G offers two types of voltage detection, “Upper” (output voltage goes low when input voltage becomes higher than reference voltage) and “Lower” (output voltage goes high when input voltage becomes lower than reference voltage). It has a maximum input voltage of 7V, a reference voltage of 5.6V and a typical voltage detection accuracy of ±1%, and is operated at a temperature range of -20 to 85 °C.

The XC6122E539ER-G has several features that make it suitable for various applications. It offers an automatic reset function, which can reset system when an external power supply is lost or over-current and over-voltage are reached, ensuring system reliability and extended life. With its fast response time of 200uS (typ.) or 1mS (max.), the XC6122E539ER-G is capable of instantaneously responding to sudden changes in system conditions. It also offers reset delay control, adjustable output drive capability, and low output drive current.

The XC6122E539ER-G is a versatile supervisor IC that finds applications in various system fields. It is used in battery and chipset protection for portable device such as smart phones, digital cameras and MP3 players. It is also commonly used in system monitoring and power management for computer and digital devices, including motherboards, industrial computers, set-top boxes and LCD monitors. Other applications include automotive systems where the XC6122E539ER-G is used for power system, charging, and ECU control.

The working principle of the XC6122E539ER-G is based on the comparison of an external power source voltage with a pre-determined reference voltage, which is set by external resistors. When the input voltage is higher than the reference voltage, the output is low (Upper detection), and when the input voltage is lower than the reference voltage, the output is high (Lower detection). In the case of the XC6122E539ER-G there are two detection thresholds, one for over-voltage and one for under-voltage. When either of these thresholds is reached, the IC will output its signal to the reset pin.

In short, the XC6122E539ER-G is a low power, precision voltage detector supervisor IC capable of monitoring power, resetting the system and offering protection from power supply losses and over current or over voltage operation. Its main applications include battery and chipset protection for portable devices, system monitoring for computers and digital devices, power management for automotive systems and so on. The XC6122E539ER-G is a reliable and optimal solution for system supervision and long life operation.
