PMIC – Supervisors refers to power management ICs, which are specialized integrated circuits used to combine and oversee the functioning of the electronic components of a system. These ICs become increasingly important in power-sensitive systems where optimization, monitoring and protection are required. The TC54VN4202ECB713 is one of these PMIC - Supervisors, a high voltage/low voltage supervisor for high temperature purposes.The TC54VN4202ECB713 is a CMOS 3.3V/5V device designed to monitor one or two supplies independently or in hierarchical. It is designed to activate a reset signal in case of overvoltage or undervoltage conditions, in order to protect the microcontroller. It also has an active-high reset signal with maskable polarity.The TC54VN4202ECB713 provides a series of functions designed to optimize power consumption in various applications. It is capable of detecting overvoltage and undervoltage, and of providing UVLO (Under Voltage Lock Out) and POR (Power On Reset). Furthermore, TC54VN4202ECB713 provides active-low maskable Watchdog and manages watchdog reset inputs. It also has a RESET signal with configurable polarity. It also includes an open drain output with drain circuit that helps generate a reset signal with an adjustable threshold.In terms of applications, the TC54VN4202ECB713 is suitable for portable and industrial systems due to its wide operating temperature range and its high voltage threshold capability. It is particularly useful when used in portable devices that have to be constantly connected such as cell phones, antennas or smart cards. Also, it can be used in automotive systems to monitor battery voltage, system temperature or accelerate/decelerate speed control.Furthermore, the TC54VN4202ECB713 provides convenient monitoring for protection requirements in distributed power systems and converters. Also, it is suitable for use in applications such as switching mode power supplies and special dedicated power supplies.In terms of its working principle, the TC54VN4202ECB713 has a programmable threshold voltage and hysteresis which are used to detect overvoltage and undervoltage. It also has two integrated delay periods which can be used to filter out fast transients. The TC54VN4202ECB713 has two open drain outputs which can be used as maskable input signals in order to generate reset events.Furthermore, the TC54VN4202ECB713 has a watchdog timer with variable time-out period ranging from 0.25 to 48 seconds. This timer can be used to generate a reset after a certain period of time if the system fails to respond to the programmed threshold values. In case of under-voltage conditions, the TC54VN4202ECB713 can also generate a RESET signal.In conclusion, the TC54VN4202ECB713 is a high performance and reliable power management IC that is suitable for applications requiring temperature stability and wide voltages monitoring. It can be used in various systems such as portable devices, automotive systems, distributed power systems and special power supplies. It provides a comprehensive set of functionalities and features designed to reduce power consumption, optimize performance and protect the system from overvoltage and undervoltage conditions.
