Introduction

The XC6119C36ANR-G is a high performance, low cost supervisor from Texas Instruments (TI). It is part of their Supervisory Circuits family of products, and serves as an ultra low power reset controller with advanced power management capabilities. This device can be used in a wide variety of applications, including automotive, industrial, and consumer electronic products. It is designed for use on micro controllers and in system-on-chip (SoC) designs. Additionally, the XC6119C36ANR-G can be used in applications where the system must be able to recover from a spurious reset condition, providing the necessary power management features to do so.

Application Field

The XC6119C36ANR-G supervisor is used in applications where it is necessary to protect a system’s processor from reset due to external use or power supply disruptions. It features a wide range of features, including watchdog/timers, reset outputs, and an embedded state machine to monitor and manage reset events. It also includes an integrated voltage monolithic leak detector (VMLD) circuit that can detect and reset a system in the event of low voltage.The XC6119C36ANR-G supervisor offers the capability to target a specific voltage level for system reset and provide various combinations of outputs to protect the system from excessive power consumption or overvoltage. It comes with an integrated 5.3V clamp diode, adding to the supervisor’s versatile protection capabilities.The XC6119C36ANR-G can also be used in embedded applications, such as in SoCs and micro controllers, where power management and/or protection of system resources is necessary. It can be used to control the power supply to certain system components, reset specific devices, and provide reset countermeasures, further contributing to system integrity.An additional feature the XC6119C36ANR-G offers is the ability to access and control power-up, power-down, and reset timing. This can prove useful in advanced applications, such as where a processor must be reset and restarted.

Work Principle

The XC6119C36ANR-G utilizes an internal voltage detector circuit that triggers a reset output if it detects an event, such as an excessive voltage, or a sudden disruption or decrease in power or voltage.The XC6119C36ANR-G is designed to provide a precise reset output when a difference in the input power between its two power pins exceeded the specified threshold level. Upon detecting an event, the XC6119C36ANR-G will output a low level reset signal to the system, effectively resetting the system.The XC6119C36ANR-G also offers an internal Watchdog Timer/Counter that can be used to monitor systems or clock signals, in order to protect the system from runaway or unexpected behavior. It includes up to 8-bits of counter/watchdog configuration, allowing users to adjust the reset the timeout and number of retries, providing flexibility in reset timing.The XC6119C36ANR-G also features an embedded state machine that can detect system reset events and initiate a reset output at appropriate times. This allows the supervisor to detect not only reset signals, but also to reset the system after a variety of conditions. The state machine is also used to manage power-up and power-down timing, allowing the XC6119C36ANR-G to initiate the reset at specified intervals and in specific order.

Conclusion

The XC6119C36ANR-G is a versatile supervisor from Texas Instruments, optimized for low power and advanced power management capabilities. Its application fields include automotive, industrial, and consumer electronic applications, as well as embedded micro controllers and SoC designs, making it a popular choice for applications requiring power management and/or reset protection. Its working principle is based on an integrated voltage detector circuit that triggers a low level reset signal in the event of an external trigger or disruption in power or signal, as well as a watchdog/timer, reset output, and embedded state machine for additional features. With these features, the XC6119C36ANR-G is an ideal choice for a variety of device applications.
