PMIC (Power Management Integrated Circuit) is a family of integrated circuits or devices which provide power management in various applications. Supervisors are PMICs which are designed to optimize power consumption, prolong operating life, distribute power and monitor power supply system integrity.

The XC6121D328MR-G (hereafter referred to as “the XC6121”) is a supervisor IC (Integrated Circuit) from the XC6121 family of products. It is suitable for many types of battery and power-sensitive applications.

Application Field

The XC6121 is a reliable and versatile device, making it suitable for use in a wide range of applications. It is commonly found in:

• Consumer electronics (e.g. Digital cameras and gaming consoles)
• Industrial systems (e.g. Programmable Logic Controllers)
• Medical devices (e.g. Surgical monitoring systems)
• Automotive systems (e.g. Hybrid vehicle control systems)

The XC6121 can adapt to any application environment, enabling it to provide reliable, long-term monitoring and power management.

Working Principle

The XC6121 offers a variety of features to help optimize power management for battery and power-sensitive applications. The main purpose of the XC6121 is to monitor the voltage of the power supply and take appropriate action if the voltage deviates from preset parameters. The XC6121 operates with a wide input range from 2.5V to 6.36V, giving it a wide range of applications.

The XC6121 is designed to detect the voltage and current of a power source and if the voltage or current becomes too low or too high, the XC6121 will enter a low-power mode or trigger an interrupt. Additionally, the XC6121 includes protection for over-voltage, under-voltage and over-current situations. The XC6121 offers a variety of reset output options, including delay and pulse width modulation (PWM) reset. Additionally, the XC6121 can support input from a remote voltage sensing line, allowing it to accurately monitor the power supply.

The XC6121 also offers a variety of other features, such as:

• Wide temperature range (-40C to +125C)
• Wide input range (2.5V to 6.36V)
• Power down mode to reduce power consumption
• Built-in reset circuit and timer
• Flexible reset options (delay, PWM)
• Low quiescent current consumption
• Internal over-voltage, under-voltage and over-current protection
• Built-in leakage current limit
• Early-power fail detection capability

The XC6121 is a versatile, robust IC, providing an effective and reliable solution for monitoring and managing power in battery and power-sensitive applications.

Thanks to its many features and its wide temperature range, the XC6121 is an excellent choice for applications where efficient power management and reliable performance are key. Its low quiescent current consumption and flexible reset options make the XC6121 an ideal choice for battery-operated devices and other power-sensitive applications.
