PMIC - Supervisors encompass a wide range of integrated circuits (ICs) used for various specific purposes in electronics and computing systems. One specific application is the XC6124 A740ER-G supervisor IC. This IC is designed for embedded systems and is used for multiple system functions like real time clock operations and reset management.

On powering on an embedded system, it needs to perform an initialization of system registers and variables. This initialization process is known as reset. The XC6124 supervisor is used to manage resets in the embedded system. Apart from reset management, other functions the XC6124 supervisor handles are:

• Low voltage monitoring necessary during system power up and reset.
• Real-time clock (RTC) operations.
• Brown-out detect/reset circuitry.
• Configuration watch by checking configuration register values on power up.

The XC6124 supervisor has multiple independently-programmable sources for reset events. It has a power-on reset (POR) source, a manual reset input, a watchdog timer reset source, and a real-time clock reset source. Each of these sources can be used for system initialization and reset management.

The XC6124 supervisor also has a real-time clock (RTC) source, which can be used to generate an interrupt and can be used to enable or disable system clocks or peripheral devices based on the programmed values of the RTC. It also has a configuration watch feature which can be used to perform a CRC or secure boot on the microcontroller’s configuration registers.

The XC6124 supervisor implements a range of different on-chip features like temperature/voltage monitoring, watchdog timer, low voltage detection and two output I/Os. It has multiple power management options which can be used to manage system power up, power down, and reset. Additionally, it has an optional ROM addressed area which can be used to store codes or data that can be used during various operations.

The XC6124 supervisor can detect low voltage events like brown-outs, and in the event, of such a situation, it can immediately reset the microcontroller’s system context. It also has over-voltage detection, which can be used to prevent any damage to the circuit or component due to an over-voltage situation. It also has an active high and active low output pins which can be used to control the switching of loads or indicator lamps.

The XC6124 supervisor has application in various types of embedded systems including communication systems, industrial control, energy management, automotive and consumer electronics. The supervisor is designed to work with a wide range of voltage ranges from 1.6V to 5.5V. It is available in various package options including SOP, DFN and QFN packages.

The XC6124 A740ER-G supervisor IC is a powerful and versatile tool that can be used for reset management and real-time clock operations. It has multiple power management options and multiple independently-programmable sources for reset events. It also has active low and active high output pins which can be used to control the switching of loads or indicator lamps.
