Overview
Power Management IC (PMIC) is a key component for controlling power of a system. PMIC-Supervisors are an essential part of power management circuits as they provide important protection and monitoring functions for operation of systems. XC6121E640ER-G is a high performance CMOS voltage supervisor and reset generator that is manufactured by IXYS Corporation. This high-performance supervisor has a wide operating temperature range from -40°C to +85°C , making it suitable for applications that require extended environmental operating temperature limits.XC6121E640ER-G Features & Benefits
XC6121E640ER-G features a wide input voltage range of 2.8V to 5.5V and provides three main circuit blocks: voltage supervisor, reset generator and watchdog timer. Its voltage supervisor has a factory programmable reset point threshold (VTH)value with a resolution of 125mV. It also features a push-button reset input pin and a reset output pin (RESET) that can be used to generate a RESET waveform. The watchdog timer circuit is used to detect a timeout condition if the monitored waveform does not exceed a pre-determined time period. The timer circuit output will then generate a reset output signal.The XC6121E640ER-G also includes a watchdog detector to detect a non-functioning microprocessor. The non-functioning microprocessor can be reset when the watchdog detector circuit detects the process issue and output a low voltage signal. This feature helps to ensure any identified problem is still being monitored as the watchdog detector circuit continuously checks the emission of the proper waveform.XC6121E640ER-G Application Fields
The XC6121E640ER-G is suitable for use in a wide range of applications such as in telecom or enterprise equipment, medical and industrial systems, home networking platforms, wired and wireless routers, servers, optical network units and industrial automation. As it operates at a wide operating temperature range and is designed to detect a wide range of voltage supply issues, the XC6121E640ER-G can be used in many system designs across a range of applications.XC6121E640ER-G Working Principle
The XC6121E640ER-G provides a wide range of protection and monitoring functions for the operation of systems. It monitors all the voltages of the system, including standby and working voltage levels. At power on, a sense voltage input is applied to the XC6121E640ER-G to detect the power supply failure. This supervisor and reset generator can detect a power supply failure condition and automatically reset the system when the VTH (reset point threshold value) is reached.The watchdog timer circuit monitors the waveform and generates a reset signal if the waveform exceeds a predetermined time period. The watchdog detector circuit is used to detect any issues with the microprocessor and resets the system if a timeout condition is detected. The reset output pin is used to reset any logic circuits and the RESIN pin is used to reset any device.Conclusion
XC6121E640ER-G is a high-performance supervisor and reset generator manufactured by IXYS Corporation. It is suitable for use in a wide range of applications and offers a wide operating temperature range. Its key features include wide input voltage range, voltage supervisor, reset generator and watchdog timer circuit, and watchdog detector circuit. Its working principle is to detect power supply failure and reset the system when the VTH (reset point threshold value) is reached. As it performs important protection and monitoring functions, the XC6121E640ER-G is an essential part of power management circuits.The specific data is subject to PDF, and the above content is for reference
