The XC6123E633MR-G is a supervisor device in the Power Management Integrated Circuit (PMIC) range, and has numerous applications within electronic devices. It is specifically designed to monitor power supply voltage levels, detect anomalies, and reset microprocessors, circuits and other components accordingly. In this article, we will discuss the application field and working principle of the XC6123E633MR-G PMIC supervisor.

As previously mentioned, the XC6123E633MR-G is a PMIC supervisor which is designed to monitor and protect microprocessors from unexpected and unwanted power fluctuations. It can also be used to protect low voltage circuits, such as those found in portable devices like mobile phones, tablets, and so on. The XC6123E633MR-G can be used in various applications, including power conversion, intelligent control, communications, motor control, and other control fields.

The XC6123E633MR-G PMIC supervisor features an adjustable detect voltage, with a wide range of 5.9 V down to 1.2 V. It also features a reset signal voltage (RESET_) which is set at 1.2 V. This voltage is used to assert the reset signal when the monitored voltage drops below the threshold value. Additionally, the XC6123E633MR-G can detect internal supply voltage drop events that might occur due to power on/off events, short circuit, or other conditions. As such, it can protect devices from glitches, voltage droops, and other power anomalies that can affect sensitive electronics.

In terms of its working principle, the XC6123E633MR-G PMIC supervisor works by comparing the monitored power supply voltage level with the internal reference voltage. If the monitored voltage level drops below the reference voltage, the reset signal (RESET_) is asserted. Once the tracked voltage level returns to a valid level, the reset signal is de-asserted and the monitored components will function correctly.

The on-chip reset time delay can also be configured using a capacitive network to adjust the time delay between the reset signal assertion and the reset signal de-asssertion, based on user requirements. Additionally, the XC6123E633MR-G also features an active high drain which can be used for periodic monitoring of the power supply status. This can be used for devices that operate in a continuous powered mode.

In conclusion, the XC6123E633MR-G PMIC supervisor is an essential device for protecting sensitive electronics from unwanted power anomalies and drops. Its adjustable detect voltage, reset signal voltage, and on-chip reset time delay make it suitable for a wide range of applications, from power conversion to intelligent control.
