The XC6108N14BGR-G is a highly accurate, low-quiescent-current Supervisory Integrated Circuit (SIC) manufactured by ON Semiconductor and designed to support various digital circuits and systems. This single 3-pin SIC contains a voltage monitor, digital reset monitoring, and voltage clamping circuitry, making it a versatile and reliable solution for a variety of applications.

Application Field

The XC6108N14BGR-G offers an excellent solution for low-voltage monitoring in battery-powered systems and telecommunication devices. Its small form factor (3-pin SOT-25) makes it an ideal choice for operation on a wide range of power supply voltages and line conditions. Additionally, its voltage clamping circuit provides protection against ESD and latch-up events, making it suitable for end products within the automotive, industrial, and medical sectors.

Compared to other similar products, the XC6108N14BGR-G stands out due to its low quiescent current of 7 µA. This feature makes it a great choice for portable or battery operated systems and environments that require energy efficiency. Furthermore, the device can be configured to operate in a variety of Control Modes, allowing selectable Output Control, asserts stability and control in power sequencing applications, and provides reset capabilities for digital systems.

Working Principle

The XC6108N14BGR-G can operate from a wide range of power supply voltages ranging from 1.8V to 13.2V. It contains a voltage monitor, digital reset monitoring, and voltage clamping circuitry for reliable operation in varying conditions. It also has a wide monitoring range between 3.2V and 13V, making it suitable for multiple supplies.

The voltage monitor circuit is used to monitor the power supply voltage and generate a reset signal when the monitored voltage drops below a specified level. This reset signal is then routed to Reset pins (RESET_L and RESET_H) of the SIC, where it can be used to reset externally connected digital systems. Additionally, the SIC can be configured to operate in active-high or active-low output polarity, allowing various control applications.

The voltage clamping circuit in the XC6108N14BGR-G is used to protect the external components connected to the SIC\'s RESET_L and RESET_H pins. The clamping threshold of this circuit can be preset using the VCAP pin of the device, making it ideal for operation in high ESD conditions.

Apart from the reset and voltage clamping functions, the XC6108N14BGR-G also offers reset monitoring and debouncing capabilities. The device contains a delay timer that prevents false reset signals from occurring due to supply voltage fluctuations. This delay timer can be reset using the RESET pin, allowing the device to be used in a variety of applications.

Conclusion

The XC6108N14BGR-G is a robust and reliable solution for a variety of low-voltage monitoring applications. Its low quiescent current consumption and voltage clamping features make it ideal for operation in battery-powered and automotive systems. Additionally, the SIC can be configured to operate in multiple output control modes, providing reset control and protection against ESD and latch-up events. As a result, the XC6108N14BGR-G is a useful choice for controlling and monitoring power supplies and digital systems.
