PMIC - Supervisors: MXD1818XR23+T application field and working principle

PMIC supervisor chips, such as the MXD1818XR23+T, are highly integrated circuits designed to provide protection and supervision functions within an integrated power management system. The MXD1818XR23+T is a high performance supervisor varistor (MOV) integrated circuit which provides overvoltage, overcurrent and undervoltage protection under various operating conditions. It is an ideal integrated device for many applications and is particularly well suited for medium voltage power system protection.

The MXD1818XR23+T supervisors provide several features for application flexibility, including a wide operating supply voltage range of 1.8V to 23.5V, a 0.5 ohm switch on resistance (RDS-on) peak voltage and current capability and an 80 VAC operating temperature range. It also features a transient response threshold of 0.5V and a maximum Vout of 150V.

The MXD1818XR23+T supervisors can be used in a variety of applications, from low voltage to medium voltage power protection. It can be applied in automotive and industrial power management, switchmode power supplies, home appliances, industrial tools, emergency units and UPS systems. It is also suitable for portable electronic applications and embedded electronic systems.

The MXD1818XR23+T supervisors provide a variety of features to ensure superior performance. It provides superior overvoltage protection due to its fast response time and low quiescent current. It also provides voltage, current and temperature sensing, soft start and overvoltage protection. This makes it suitable for applications such as switchmode power supplies, overvoltage and undervoltage protection, and low voltage protection.

The MXD1818XR23+T supervisors use an integrated MOV which provides overvoltage and overcurrent protection, and an overvoltage comparator with a response threshold of 0.5V. The supervisors also feature a current sense amplifier with a gain of 56 dBs and a maximum peak voltage of 150V. This ensures superior performance in a wide range of applications.

The MXD1818XR23+T supervisors also feature a built-in timer for a soft start. This improves the power supply system efficiency and extends the life of the system’s components. The supervisors also include over-temperature and over-current protection to protect the system from excessive heat or power. The timer can be adjusted to reduce the hot start of the system.

In conclusion, the MXD1818XR23+T supervisors provide a wide range of features for medium voltage power system protection. It features an integrated MOV for superior overvoltage and overcurrent protection, a current sense amplifier for superior performance, and a built-in timer for soft start. The supervisors are suitable for a variety of applications, including automotive and industrial power management, switchmode power supplies, UPS systems, and embedded electronic systems.
