PMIC - Supervisors: TC1270ANRVCTTR Application Field and Working PrincipleIn the field of Power Management Integrated Circuit (PMIC), different products have different application fields and working principle depending on the purpose. In this article, the application fields and working principle of TC1270ANRVCTTR are introduced to provide readers a better understanding of it. TC1270ANRVCTTR is a low voltage supervisor specifically designed to monitor multiple voltage lines in PMIC applications. It is especially useful in applications with multiple power supplies that must be monitored or reset in case of a fault. Typical applications that TC1270ANRVCTTR is used include personal computers, servers, network equipment and embedded controllers. The working principle of TC1270ANRVCTTR can be divided into four stages. At the first stage, the input voltage is compared against the upper and lower trip thresholds which are user-programmable against a reference. The second stage is the trip-point logic circuit which detects the amount of time between the asserted trip condition and the de-asserted reset signal. The third stage is the power-on reset comparator circuit which compares the reset voltage of the device with the reference voltage. The fourth stage is the reset generator which generate the reset signal. In terms of features, TC1270ANRVCTTR is a highly integrated device with several creative aspects. It is capable of monitoring up to 16 voltage sources with one device, and supports user-programmable reset active/inactive levels, reset duration, auto-restart and delay. Most notably, TC1270ANRVCTTR features an integrated delay allowing the reset of the system once all its rails have converged. It also supports I2C and SPI output which provides drive control capability and monitoring of voltage levels. In addition, TC1270ANRVCTTR has numerous desirable characteristics, including strong precision accuracy, high tolerance of up to ±2.5% and fast reactivity. It has a wide range operation voltage of up to 8V, which enables complex systems to be efficiently protected from brownouts and power faults. Overall, TC1270ANRVCTTR provides an exceptional combination of features and performance that is cost effective for any high performance system. In conclusion, TC1270ANRVCTTR is a suitable device for PMIC applications where multiple voltages need to be monitored and reset. It is highly integrated, user friendly, cost effective and provides an impressive combination of features and performance.
