PMIC supervisors are integrated circuits that are used to ensure that a system’s operational parameters are within safe and reliable limits. The XC6122C733MR-G is a voltage supervisor IC specifically designed for reliable power management in automotive, consumer and medical applications. The following article will discuss the XC6122C733MR-G’s application fields and working principles.

Application Fields

The XC6122C733MR-G is a two terminal microprocessor-controlled reset circuit designed for interfacing with microcontrollers. The device is specifically designed to monitor inrush current limiting, over-current protection and low-battery detection. It features an adjustable delay time, a built-in trimming circuit and a wide voltage range. Additionally, the device has a power on reset function, a low voltage/discharge interrupt function and a watchdog function.

The XC6122C733MR-G is suitable for automotive, consumer and medical applications. In automotive applications, the device is used to monitor voltage discontinuity during battery connection, inrush current limitation, low-battery voltage indication, UPS battery discharge indication and idle shutdown. In consumer electronics applications, it is used to prevent sudden power supply failure due to overloaded circuit, protect against voltage transients and to provide reset after a system or power line malfunction. Lastly, in medical applications, it is used to maintain reliable power supply in medical devices and to provide over-current protection.

Working Principles

The XC6122C733MR-G works by monitoring the voltage on its power line input. It is equipped with a programmable delay timer and a built-in trimming circuit. When the power line voltage exceeds the predefined upper threshold, the device triggers an internal reset circuit to reset, or power-on reset, the digital circuitry. When the power line voltage falls below the predefined lower threshold, the device triggers an internal reset circuit to reset, or low-voltage/discharge reset, the digital circuitry. Additionally, the device has a watchdog timer that is used to prevent system lockup and reset the system if the processor does not respond in a reasonable amount of time.

The XC6122C733MR-G is a versatile device that provides reliable multiple levels of protection against voltage discontinuities in a variety of automotive, consumer and medical applications. The device has an adjustable delay time, low-voltage/discharge reset, power on reset and watchdog functions, and works by monitoring power line voltage and triggering internal reset circuits when predefined thresholds are crossed.

In summary, the XC6122C733MR-G is a voltage supervisor IC specifically designed for reliable power management in automotive, consumer and medical applications. It is used to monitor inrush current limiting, over-current protection and low-battery detection and features an adjustable delay time, a built-in trimming circuit and a wide voltage range. Additionally, it has a power on reset function, a low-voltage/discharge interrupt function and a watchdog function. The device works by monitoring the voltage on its power line input, and triggering internal reset circuits when certain predefined thresholds are crossed.
