XC6121A747ER-G

PMIC (Power Management IC) - Supervisors are a type of integrated circuit (IC) dedicated to monitoring the voltage of a power supply. The XC6121A747ER-G is an example of this technology. This supervisor IC acts as an overvoltage protection and reset generation device, providing an accurate and reliable system power-on device protection.

The XC6121A747ER-G is used to monitor the voltage of a power supply, attention the power supply when its voltage crosses the predetermined voltage value, and then reset the power supply to the normal operating voltage. It is commonly used for automotive electronics or other contexts requiring a reliable source of power.

The operating voltage range of XC6121A747ER-G is from 3.0V to 19.2V. It features a programmable reset threshold voltage coverage from 2.3V to 5.3V, and the power-on reset delay time can be adjusted from 0.02 seconds to 2.5 seconds. It also supports a protection function for overcurrent / over-voltage / under-voltage and over-temperature.

The XC6121A747ER-G adopts the Super-Power-On-Reset technology, combining the advantages of the traditional power-ON reset circuit and the simple voltage comparator circuit, greatly improving the accuracy and stability of reset voltage, and at the same time increasing the reset threshold voltage range.

The XC6121A747ER-G contains a reset timer, and its advanced reset toggle flip-flop circuit (RTFF) technology can completely eliminate the heat-up reset phenomenon caused by a single power-on reset circuit. The higher current capability and lower voltage drop of XC6121A747ER-G can provide power-on reset signals with longer pulse width and lower drop voltage characteristics.

The XC6121A747ER-G integrates several peripheral components, including over current protection circuit, over voltage protection circuit, over temperature protection circuit, circuit for resetting power supply output, etc. The over-current protection (OCP) circuit monitors the presence of a load current, if the current is higher than the preset value safety, then it will immediately send out a signal to shut down the power supply, so as to prevent the external system from damage.

The XC6121A747ER-G also supports a variety of analog and digital resolutions that can control reset, reset timer and over temperature comparator functions. Its processing power can support complex power systems and achieve more accurate and powerful control. The XC6121A747ER-G is available in WQFN and small SOP packages, and its compact design can easily fit the existing automotive in-vehicle boards, improving the performance of existing products.

In conclusion, the XC6121A747ER-G is a high performance, reliable power management IC from NXP. It can monitor the voltage and power supply of a power supply, keep it stable and safe, and provide a variety of process and digital resolutions. It is widely used in automotive electronics or other context requiring a reliable source of power.
