Along with its increasing demand in market, there comes out a new type of Supervisory Circuit, MAX6869UK21D3S+T, which can be applied in batteries, power management, wireless communications, and audio devices. From its name, we know that it is a supervisory circuit(SC) and its specific application is in PMIC – Supervisors, so let’s get to know more about it.

PMIC-Supervisors are electronic components that are mainly used to guarantee the start-up of the system and monitor its operation as an engineer. It can detect the power system of the system, prevent out of power reset, reduce the load corresponding to the system, and detect the voltage changes of the system in real time. MAX6869UK21D3S+T, as one of the PMIC-Supervisors, including two components: MAX6869 and the associated level MOSFET. It features precision voltage monitor with selectable three thresholds (1.8V, 2.9V, 3.63V), manual or automatic reset production, selectable push/ pull or open-drain reset output, active low or active high reset output and low power dissipation.

MAX6869UK21D3S+T is featured by the integrated circuit of MAX6869, which is specifically designed to monitor system power supply and the level MOSFET. The MAX6869UK21D3S+T is designed to monitor three thresholds – voltages of 1.8V, 2.9V, 3.65V – selectable with a reset sequence that triggers reset when the selected level is dropped below the operating voltage. The voltage level data from the chip is then used to operate the level MOSFET, which can either pull the reset line low(active low) or pull it high(active high). When the voltage level reaches the threshold, the level MOSFET will turn off, holding the reset line in its appropriate state.

MAX6869UK21D3S+T provides several benefits, such as low power dissipation, low quiescent supply current (1.2uA typ.), manual or automatic reset production, selectable push/ pull or open-drain reset output, active low or active high reset output, high level reset accuracy, and fast response time (200ns typ.). It is designed to work with the microcontrollers that are commonly used in the industry, such as the 8051 microcontroller.

MAX6869UK21D3S+T can be widely applied in different fields, such as wireless communications, audio devices, batteries, and power management. It is widely used in the system boards of electronic devices, as it ensures that the microcontroller starts up safely and also monitors the operating status of the system in real time. In wireless communications, MAX6869UK21D3S+T can be used as a voltage monitor to detect the status of the power supply, making sure the proper working condition of the system, as well as avoiding signal loss and other mistakes.

In conclusion, MAX6869UK21D3S+T is a reliable supervising circuit and its a trendy device in the PMIC-Supervisors field. It can monitor the voltage levels and detect the power system of the system, prevent out of power reset, reduce the load corresponding to the system and detect the voltage changes of the system in real time. It has a wide application in different fields and provides several benefits, such as low power dissipation and low quiescent supply current.
