PMIC (Power Management Integrated Circuits)Supervisors are semiconductor integrated circuits that support the management and distribution of power, providing safe and reliable power control, monitoring, and protection for electronic systems and components. The XC6124D748MR-G is a PMIC supervisor with a variety of features and applications. This article will discuss the application fields and working principles of the XC6124D748MR-G.

The XC6124D748MR-G is integrated into multi-output systems as a power supply IC to ensure safe and reliable power control, monitoring, and protection at each output. It can regulate maximum output voltages and currents up to a preset level, prevent over-voltage and over-current, and detect fault conditions. It typically supports output voltages of 5 V, 12 V, 24 V, and negative 12 V, and supports maximum output current of up to 20 A. It is therefore suitable for applications such as industrial electronics, medical and safety equipment, office equipment, automotive electronics, telecommunications, power supplies and computers, to name a few.

In terms of working principles, the XC6124D748MR-G provides supervisors and protection functions by using an internal comparator and open collector transistor output. As shown in Figure 1, the XC6124D748MR-G uses an internal voltage reference VREF, which sets the over-voltage/over-current protection threshold. When the output voltage and current exceed the threshold, the voltage comparator compares the threshold with the set voltage/current, and outputs a low-level signal through an open-collector transistor. This signal is fed to an external logic circuit to indicate a fault condition. In addition, the XC6124D748MR-G supports a variety of power management functions including current limit, under-voltage/under-current detection, switching delay, over-current alarm, and temperature warning.

The XC6124D748MR-G also features a low dropout voltage, allowing it to maintain low voltage and output current levels. In addition, it features a low power enabling circuit so that only a small current is needed for power-on-reset operation. The XC6124D748MR-G is also power efficient, reducing power dissipation and overall system temperature. Finally, the XC6124D748MR-G is designed to work over a wide range of temperatures (from -40°C to 125°C) and is available in a small 6-pin SOP package.

In conclusion, the XC6124D748MR-G is a versatile PMIC supervisor that can be used in a variety of applications. It features an internal voltage reference which sets an over-voltage/over-current protection threshold, as well as a variety of other power management functions. It has a low dropout voltage, low power enabling circuit, and is power efficient. The XC6124D748MR-G is designed to work over a wide temperature range and is available in a 6-pin SOP package.
