The XC6122F628ER-G Supervisors PMIC (power management IC) is designed to protect systems against power supply failures and protect against damaging overvoltage levels caused by faults in other components. It is tailored to interface between applications and the power supply network to provide a superior level of protection. As such, the XC6122F628ER-G holds an important position in the system, for it helps to ensure reliable and power supply against unwanted, destructive stimulation.

The XC6122F628ER-G offers a comprehensive portfolio of protection functions, from undervoltage, overvoltage, overcurrent, over temperature, reverse polarity, and current limit protection, to power sequencing and noise filtering. The device is manufactured in a low-profile SMD package which is suitable for space-constrained systems.

Applications for the XC6122F628ER-G Supervisors PMIC are varied, as much of its success is in its flexibility and ease of integration into many different power systems. The device is suitable for many Industrial, Automotive and Consumer applications, such as home audio, HVAC and white goods, power tools, and power supplies, as well as applications with tight size requirements.

The XC6122F628ER-G is a single OTP (one time programmable) device, containing a main control IC, a UVLO (Under Voltage Lock Out) and an OVP (Over Voltage Protection) IC. It includes input under voltage protection, output overload and short circuit protection, and protection against transients. In addition, it contains protection against reverse current, over-temperature, and overvoltage, which can be programmed using external resistors and enable/disable pins. The device features a low standby power and high interrupt levels to support applications that use high-sensitivity load controllers.

The XC6122F628ER-G provides highly accurate voltage detection and overvoltage protection (OVP) with a hysteresis voltage of 0.5V max over the desired OVP range. The device supports 3.3V, 5.0V and 12.0V Vcc supply voltage. The power supply current is limited to 11mA (nominal) by a 50µA current limit circuit, which can help to reduce power consumption when the device is in use.

The XC6122F628ER-G achieves the combination of utmost protection and accurate control of the power supply line by the implementation of several detection, control, and protection algorithms. These algorithms are used to ensure that sufficient voltage is available to support the applications in a safe and reliable manner. The device also provides a logic supply output for a variety of logic circuits. It monitors the voltage output at the correct voltage levels and provides an adjustable warning trip point that can be set to trigger when the voltage drops below its regulated trip point. It also provides a reset signal when the trip point is exceeded.

Due to the high levels of protection it offers, the XC6122F628ER-G Supervisors PMIC is the ideal choice for a wide range of industrial, automotive, and consumer applications. It can provide the necessary protection against faults, while also offering the accurate control of power supply lines required by many systems. As part of a power management system, it forms an essential element of any safety-critical or mission-critical system in which a reliable voltage supply is critical.
