XC6121C440ER-G

The XC6121C440ER-G is a high-performance supervisor IC (Integrated Circuit) designed for use in system power-on and brown-out circuits. It is a single-channel supervisor IC with a watchdog timer and reset function, and can be used to monitor system voltage and reset the system if it detects voltage abnormalities. The IC is suitable for use in mobile consumer devices, automotive, industrial and telecommunications applications.

The XC6121C440ER-G has a system reset signal output, and the timing circuit is designed with a watchdog timer. The watchdog timer can be used to keep track of the operating state of the system, and when the system runs abnormally, it can trigger a reset and restart the system, so as to ensure the normal and stable operation of the system. The XC6121C440ER-G can monitor the supply voltage conditions in the system, and if it is lower than the reference voltage range, it can generate a reset signal to start the system again. In addition, it can discriminate between low-voltage faults and power loss, to ensure more reliable system startup.

The XC6121C440ER-G is an ultra-low power consumption device. It can monitor the system voltage from 0.7v ~ 3.6v, and it consumes only 5uA of quiescent current. In addition, it has a high warning point and warning time accuracy, and can work normally in temperature range -40~85 degree Celsius. It also has a wide reset time range, from 50 µs to 2 ms.

The XC6121C440ER-G can be used in various applications, such as system startup and Power-On-Reset (POR) in mobile consumer electronic devices, automotive, industrial and telecommunications equipment. It is also applicable to low-power systems that require ultra-low power consumption and highspeed operation, such as microcontroller-based systems.

The working principle of XC6121C440ER-G is based on a comparator circuit monitoring the power supply voltage. The normal operating voltage of the system is monitored against the reference voltage. If the voltage of the power supply falls below the reference voltage, or the system operating state is abnormal, then the reset signal will be output from the device. The reset signal will restart the system, and then the system can enter the normal operating state when the voltage rises above the reference voltage.

In conclusion, the XC6121C440ER-G is a high-performance supervisor IC (Integrated Circuit) with a wide range of applications. It has excellent power efficiency and reliable reset functions, and is suitable for use in low-power systems. As a result, it is widely used in mobile consumer devices, automotive, industrial and telecommunications applications.
