The XC6124C438ER-G is a voltage supervisory and power management integrated circuit (PMIC) specifically designed for microprocessor (MPU) applications which require robust reset and power good functions.

The XC6124C438ER-G features two active-low selectable reset outputs, three active-high programmable power good outputs, and two power control outputs. It also features an adjustable voltage threshold that can be used with a conservative approach (effective reset) , as well as a low power supply current that has a minimum of ±0.25 µA.

The XC6124C438ER-G is a highly integrated device that includes a wide range of features, such as reference voltage regulation, adjustable reset timeout, programmable power-good output, power enable input and power sequencing monitor, enable inputs for reset outputs, and several other programmable features. Furthermore, the device can be used together with an external voltage reference or temperature sensor to trigger a reset, or with an external GPIO to enable monitoring of an additional power supply.

The XC6124C438ER-G is applicable for a variety of applications, including mobile phones, personal digital assistants, PDAs, digital cameras, MP3 players, automotive applications, and other battery-operated devices. The device is especially suitable for any application that requires robust reset timing and power monitoring.

The XC6124C438ER-G works by providing an adjustable power-good output (PGOOD), and two reset outputs (LOUTR and LORST) that monitor the supply voltage(s) of the microprocessor. The PGOOD output is an open-drain signal which can be used to indicate that the supply voltage(s) of the microprocessor(s) is within specified limits. The LOUTR and LORST reset outputs are active-low signals that can be used to reset the microprocessor if the voltage(s) falls below a programmable threshold. The threshold level is adjustable using the external voltage reference. Furthermore, the device provides power sequencing monitoring and power up/down control functions to ensure that the system is properly powered up, and the voltage values are within the proper range.

The XC6124C438ER-G provides a wide range of features and functions, making it an ideal choice for applications requiring robust reset and power-good functions. The device ensures a reliable system that is powered up without any glitches and continuously monitored for proper voltage levels. Additionally, the device is also suited for a variety of battery operated applications due to its low power consumption.
