Introduction

XC6119N20ANR-G is a high-performance, low on-resistance master-slave reset IC that targets for system reset management for microcontrollers. It belongs to the PMIC (Power Management IC) family and is classified as a Supervisors. It is designed to as a low-voltage/low-current supervisor with low-power consumption, low-power reset generation, advanced reset control functions and strong fault-resilience features.

Application Field of XC6119N20ANR-G

XC6119N20ANR-G is designed for system reset and power management of microcontrollers. It is usually used in system boards, pin drivers, computer peripherals and other electronic systems with microcontroller as its core component. It is also suitable for a variety of power monitoring equipment, for example server racks, motherboards, HVAC systems and even DC to DC regulators, because of its voltage and current threshold monitoring capabilities. It allows system designer to reduce component count and board space, and improve system reliability through a reliable and device-controlled reset and power management.

Working Principle of XC6119N20ANR-G

XC6119N20ANR-G begins to perform its functions when the power supply is connected. It can recognize when there is an issue with voltage, and this issue can be provided with pre-defined manual reset or watchdog timer. Upon the issue happened, XC6119N20ANR-G can detects and generates an active-low reset after a programmable interval. Then, it will reset the microcontroller and bring it back to its initial state, setting all the registers and memory back to its initial values. Once the problem is solved, it will stop the reset process and resume its normal operation.

Also, XC6119N20ANR-G comes with thermal shutdown capabilities. It works along with the system hardware to sense temperature threshold and react with a hardware reset when temperature goes above a certain level. This prevents the system from damaging itself due to unexpected temperature increase.

Also, XC6119N20ANR-G provides de-bouncing or pulsing reset control where reset is asserted multiple times in a given time window. This provides a more precise control over system reset and helps the system resetting more reliable.

Conclusion

XC6119N20ANR-G is an important part of system reset and power management for microcontroller-based systems. It is a low-voltage/low-current supervisor IC and provides fault resilience and a wide range of reset control functions. It supports manual reset, watchdog timer reset, thermal shutdown and de-bouncing or pulsing reset control. With its advanced capabilities, it helps system designers to reduce complexities, reduce component count and improve system reliability.
