PMIC - SupervisorsThe XC6122D350MR-G is a precision reset controller IC from the XC6122 series of circuit devices from the X-chip Electronics Corporation. As such, it is used primarily in power management and integrated circuit (IC) applications where a wide input voltage range and precision output control is required. The XC6122D350MR-G offers a wide input voltage range from 2.7V up to 5.5V and provides an adjustable reset delay time from 1ms to 9.5ms. Additionally, it features an adjustable current limit, over-voltage protection, watchdog timer, multiple supply voltage thresholds and error outputs.The XC6122D350MR-G is designed to work as a reset or supervise controller in power management applications, typically replacing multiple discrete components like resistors and capacitors. Its primary job is to monitor power supply voltages and control the reset or enable signals to ensure system stability and continuous operation. The XC6122D350MR-G accomplishes this feat by sensing the supply and under/over-voltage threshold levels. When a set level is reached, the XC6122D350MR-G rapidly responds with a precision reset or enable signal to protect the system from unexpected shutdown or damages from supply voltage transients. The adjustable reset time delay offered by the XC6122D350MR-G prevents spurious resetting and eliminates system resets due to short-term fluctuations of the supply voltage. The XC6122D350MR-G utilizes an adjustable current limiter to protect the system from any excessive current consumption above a preset threshold. The over-voltage protection feature of the XC6122D350MR-G prevents system shutdowns due to over-voltages on the supply voltage. This ensures system stability and failure-free operation. The XC6122D350MR-G also features a watchdog timer circuit to monitor system operation and ensure failure-free performance.In addition to the above features, the XC6122D350MR-G is also equipped with a wide array of output signals, such as an enable signal, open drain reset output, push-button reset signal, and active-high reset output. These output signals are utilized to support power-on-reset, push-button reset and supervisor functions. The XC6122D350MR-G also offers an improved reset signal monitoring circuit that is capable of detecting multiple reset conditions in different operational modes. The XC6122D350MR-G is capable of supporting a wide range of power management applications such as battery-backed SRAM arrays, AD converters, low-power microprocessors, and programmable logic controllers. Its adjustable output delay time and wide range of output signals make it even more suitable for embedded applications. The XC6122D350MR-G also offers improved power-on-reset, push-button reset and supervisor functions to support system start-up/shut-down and restore operations in case of power supply failure. For higher reliability applications, the XC6122D350MR-G is equipped with an emergency shut-down feature for emergency shut-down of the system in case of sudden power loss. Overall, the XC6122D350MR-G offers a robust solution for precision reset and power management applications. Its adjustable features and high performance reset circuit make it an excellent choice for embedded applications and standby power circuits. The XC6122D350MR-G can also be used for comprehensive power management of industrial and consumer electronic equipment, such as portable media players, set-top boxes and other power-sensitive system designs.
