PMIC - Supervisors play an important role in regulating and protecting the power supply systems in electronic devices. The XC6122C433MR-G supervisor is a Protection and Power Management (PPM) device from the XC6122C family of Analog Devices. It is designed to protect electronic circuits from damage due to input voltage overlaps, short-circuit and over-temperature problems by providing accurate monitoring, precision fault detection and control functions.

The XC6122C433MR-G is manufactured using advanced Analog Mixed Signal CMOS (AMSCM) technology and combines all these protections within a single package. It offers an improved and consistent power system design, including all the important aspects of a total power management such as voltage regulation and input/output (I/O) current protection. This makes it an ideal device for advanced system designs that require protection while providing enhanced performance.

The XC6122C433MR-G supports a wide input operating voltage range of 4.5V to 15V and is capable of supplying up to 150mA of output current. It is available in a DIP-8-SOP and includes an internal voltage regulator and windowed watchdog timer. The watchdog timer provides a triggered reset and can be used to reset the device in the event of a fault condition and also to reduce power consumption, reducing the total system power consumption.

The XC6122C433MR-G has a wide range of features, making it an ideal choice for a variety of applications. It features an adjustable over-temperature, under-voltage and over-voltage detection, as well as an inverter, dual switching system and adjustable current limiting. It also has configurable Digital Delay/LED dimming, low-power mode, and burst-mode power saving. All these features make this supervisor suitable for a wide range of applications.

The XC6122C433MR-G’s application field mainly consists of high power audio equipment, portable medical products, UPS solutions, and powering of digital displays. Its applications include protection of high voltage systems, protection of circuits against over-temperature and power supply overloading, supply of currents to devices such as PCs, LCDs and CRT displays, as well as providing a soft-start function during device start-up. It can also be used for powering of audio systems and for motor control in vehicles.

The XC6122C433MR-G has a working principle based on a unique hybrid topology combination, which is composed of two independent voltage regulators. The two regulators independently control power supply to the system. The first regulator is mainly used to control the primary power supply, while the second regulator is mainly used to control the secondary power supply. The device constantly monitors the voltage of the primary and secondary power rails, and if an over-current or over-voltage situation is detected on either rail, the device immediately cuts off power supply to the system.

The XC6122C433MR-G also incorporates a digital Delay/LED dimming that can provide a delay for device start-up, and provides a PWM signal that can be used to dimm the LEDs. Additionally, it includes a burst-mode power saving feature that can be used to reduce total system power consumption. All these features make the XC6122C433MR-G an ideal choice for a wide range of applications.
