XC6123E516ER-G

PMIC, short for Power Management Integrated Circuit, is widely used in modern electronic products. It provides a critical element in the development of these products. The XC6123E516ER-G is a member of the PMIC family, and its application fields and working principles are about to be discussed in detail.

Overview

The XC6123E516ER-G is a low voltage supervisor IC with a quiescent current of typically only 7 μA. It is capable of monitoring multiple power supply and enable signals, switching state automatically in response to enable inputs or faults in the power supplies. A muxbus interface is also available for control and diagnostic applications.

Application Field

The XC6123E516ER-G is suitable for a variety of applications. It is often used as a monitor and supervisor in automotive, industrial, and medical electronic products.It is also suitable for use in embedded systems, where it helps detect any misbehavior of the system. Additionally, it has good compatibility with power sequencer chips as well as other ICs.When deployed in industrial systems, the XC6123E516ER-G helps provide robustness to various industrial controllers, allowing for more reliable data acquisition and processing. It is also used for monitoring battery lines in portable electronics.

Working Principle

The XC6123E516ER-G embeds multiple power voltage monitors, a watchdog timer, and an EEPROM memory. It allows users to preset multiple power supply thresholds and timeout settings. It also has a variety of output signals that could be used to control multiple circuits in the system.

The voltage monitor monitors the input voltages, and if any of them is either too high or too low, or if it goes outside a preset band, the IC will trigger a fault condition, depending on user-defined settings. The watchdog timer acts in much the same way, monitoring system timing and issuing a timeout signal if too long a time interval passes between input pulses.

The EEPROM memory stores user-defined settings so that, in the event of a fault condition, the IC can automatically switch state and resume proper operation after the fault has been cleared.

Conclusion

The XC6123E516ER-G is a low voltage supervisor IC that is widely used in modern electronics due to its multiple power monitoring and control functions. The IC has a wide range of application fields, including automotive, industrial, and medical products, as well as embedded systems. Its working principle involves monitoring input voltages and timing for possible faults, switching state upon detection of such faults, and resuming normal operation after the fault has been cleared.
