The XC6124D632MR-G is a type of PMIC – Supervisors, also referred to as PMICs, which are integrated circuits which have the primary purpose of supplying power to other components within a system. The XC6124D632MR-G belongs to a specifically designed family of Supervisors and it features a four-voltage-level supervisor with a push-pull reset output. It is widely used in industrial applications such as automotive, industrial and healthcare. This article aims to discuss the application field and working principle of the XC6124D632MR-G.

Application Field and Device Types

The XC6124D632MR-G has a broad application field which includes automotive, industrial and healthcare electronics. It helps in providing power solutions for numerous system boards, which may involve different circuit technologies such as microcontroller-based systems, digital signal processors, and analog signal chains. Considering the healthcare sector, the XC6124D632MR-G is used in insulin delivery systems, biomedical sensor devices and health monitoring systems. In the automotive industry, it is commonly used in electric or hybrid power systems, adaptive vehicle lighting, engine control systems and other automotive applications.

The device types supported by the XC6124D632MR-G includes Ultra-Low-Power (ULP) and low power, which involves a wide range of power management processes. It is also compatible with a variety of device types such as SOI (Silicon-on-Insulator), OLED (Organic Light-Emitting Diode) displays, and MEMS (Microelectromechanical Systems). Moreover, it has the capability to support a wide range of operating temperatures ranging from –40 °C to +125 °C.

Features

The XC6124D632MR-G features a 4-voltage level, CMOS-based Supervisors which provides a 0.8V to 4.6V power up and a 0.8V to 4.0V power down window. This helps in accurately monitoring the power levels and preventing any drastic changes in the system\'s power supply. It also features a Push-pull Reset output in order to reset the system\'s components in case of a power supply voltage failure.

The integrated circuit consists of two leaky current sources which are used for activating two reset outputs. The first one is connected to the VDD pin and the other one is connected to the VDDQ pin. Furthermore, the device also consists of an internal zero volts supply and a temperature sensor.

The XC6124D632MR-G is compliant with the JEDEC MO-220 package standard which helps in providing a more reliable and efficient performance. Its ultra-low-power consumption makes it a great choice for battery-powered applications. In addition, the device has a total current consumption of 2.8mA when working at a voltage of 1V. Moreover, it has a low shutdown current of 1μA and an operating time of 0.1µs.

Working Principle

The power-up sequence begins with the release of the reset signal. This is achieved during a power-on reset (POR) where the power supply voltage reaches a certain threshold. At this point, the reset signal is released and the integrated circuit is ready to start working. During this time, the voltage level on the VDD pin is monitored to ensure that it does not exceed the safe limits. In addition, the device is also capable of detecting power failures and warning about them through the reset signal.

When the power supply voltage reaches the safe limits, the reset signal is released and the internal circuit is ready to be supplied with power. The power-down sequence is similar to the power-up sequence, except that the power supply voltage is below the safe limit. At this point, the integrated circuit will send a reset signal, indicating that the power is going to be cut off soon.

The device is also capable of generating an internal voltage reference. This is done by connecting the VDD pin to the VDDQ pin, which produces an internal voltage reference that is equal to the input voltage of the device. This will help in accurately monitoring the power status and preventing power related issues.

Conclusion

To conclude, the XC6124D632MR-G is a type of PMIC – Supervisors, specifically designed to solve power supply related issues. It has wide application field and it is capable of supporting various device types and operating temperatures. Its features include a four voltage-level solution, internal voltage reference, a temperature sensor and a push-pull reset output. In addition, it has an ultra-low-power consumption and a low shutdown current. Finally, the working principle includes a power-up and power-down sequence, as well as monitoring of the power supply voltage to prevent power related issues.
