PMIC - Supervisors are a type of power management integrated circuits typically used in computing and embedded systems to detect certain events, such as loss of power, in order to take predetermined corrective action. APX803L20-14SA-7 is a specific type of PMIC - Supervisor that is used by a number of major electronics companies such as Qualcomm, Toshiba, and Qualcomm. This article will explore what this supervisor does and its various applications.

The APX803L20-14SA-7 is an advanced, low-cost, ultra-low power supervisor / reset IC. It features a robust, low-power architecture that includes an on-chip comparator, which can detect trigger levels as low as 1.2V. The supervisor comes with both active high and active low reset outputs, as well as shutdown mode nd time-delay reset. This makes the supervisor suitable for a wide range of mobile solutions, including dual-core and quad-core processors.

One of the main applications of the APX803L20-14SA-7 is power management in portable electronics. It can be used to detect power interruption, low battery voltage, under voltage condition, and overvoltage condition and take corrective action accordingly. This helps protect sensitive electronic components from damage due to incorrect power supply or supply irregularities. A supervisor also enables “power on reset” by triggering a reset output to the micro-controller or other devices. This is used to ensure proper safe boot operation. In addition, the shutdown input feature can be used for power-saving and power-down modes.

The working principle of the APX803L20-14SA-7 supervisor IC is relatively simple. The chip has two main and two optional outputs - active high, active low, and optional shut-down. When the chip is first powered up, the active high output will go high triggering the reset signal to other ICs. At the same time, the power-good signal is also released which enables normal operation. If the power is lost or the supply voltage drops below a certain level, the active low output is released which triggers the reset signal and sends it to the other ICs.

The APX803L20-14SA-7 has a wide range of applications. It is used in many devices such as digital cameras, portable devices, tablets, and portable gaming systems. In these devices, the supervisor IC helps protect sensitive integrated circuits from damage caused by power irregularities. It can also be used in other devices such as Industrial IoT, servers and other communications devices.

In summary, the APX803L20-14SA-7 is a low-cost, low power multiple reset supervisor IC. It features an on-chip comparator and robust architecture that allows it to detect trigger levels as low as 1.2V. Furthermore, it has active high, active low, and optional shut-down outputs which make it suitable for a wide range of mobile solutions. This makes the APX803L20-14SA-7 supervisor an ideal solution for power management applications in portable electronics, industrial IoT, communications devices, and many other applications.
