XC6124F734ER-G

Power management integrated circuit (PMIC) supervisors are devices used in different kinds of applications. These supervisors are designed to detect electrical faults, such as overvoltage, undervoltage, and short circuit conditions. The XC6124F734ER-G is a PMIC supervisor that is used in a wide range of applications. This article provides an overview of the XC6124F734ER-G, including its application field and working principle.

Overview of the XC6124F734ER-G

The XC6124F734ER-G is a supervisory IC from Toshiba Semiconductor. The IC provides a combination of 32 independent power-fail effective power-on/off outputs and a set of built-in reset generators used to initiate system reset sequences. The device supports a wide operating voltage range, from 3V to 18V.

Applications

The XC6124F734ER-G is designed to be used in a variety of industrial, medical, and consumer electronics applications. The device can be used as a gate liner for power-off protection to prevent accidents during power down. It can also be used as an inrush current limiter during start-up, which limits the peak inrush current and reduces or eliminates overvoltage protection on devices. The XC6124F734ER-G is suitable for a broad range of applications, including telecommunications and data communications, factory automation, and household appliances.

Working Principle

The XC6124F734ER-G is designed to provide a continuous monitoring of the power supply. The device has an internal voltage sensing circuit that can detect a voltage drop below a predetermined level, as well as an overvoltage condition. When the monitoring circuit detects a fault condition, it will generate an appropriate reset signal and initiate a system reset sequence. The reset generator provides voltage reset, time reset, and window reset outputs.

The device also has an internal watchdog timer that can detect a system malfunction. The watchdog timer can be used to automatically reset the system after a predetermined period of time if the system does not detect any activity from the microprocessor. The watchdog timer can also be used to prevent system malfunction due to temporary electrical noise or transient faults.

Conclusion

The XC6124F734ER-G is an effective power-on/off supervisor with built-in reset generator and watchdog timer. The device offers low power consumption and can be used in a wide range of industrial, medical, and consumer electronics applications. Its built-in voltage sensing, reset generator, and watchdog timer make it ideal for applications that require reliable power management.
