ADM1186-2ARQZ is a low power supervisor from the PMIC (Power Management IC) category of electronic components. It is a monolithic integrated circuit that is used to monitor reset conditions and power management activities in a variety of electronic applications.

The ADM1186-2ARQZ incorporates a wide range of features and functions, including an integrated regulator, under-voltage detection, over-current detection, pushbutton reset and an active discharge transistor. The active discharge transistor is used to drain off the stored energy in the output capacitor, to ensure that the reset circuit works properly.

The ADM1186-2ARQZ is a low-power supervisor that works with a wide range of input voltages ranging from +2.25V to +5.5V. It provides a wide range of reset voltage thresholds to support various reset conditions. The reset time is typically 3ms, with a maximum reset time of 10ms.

The ADM1186-2ARQZ is suitable for battery-backed applications in industrial, communication and consumer electronic products, as well as automotive, computing and embedded controllers. The device is used in applications where the system needs to be held in reset for a few milliseconds in order to ensure reliable system operation.

The working principle of the ADM1186-2ARQZ is based on the application of a low-side switch to control the flow of current from the output capacitor to the system supply voltage. The switch is enabled in order to allow the current from the reset capacitor to flow to the system supply voltage. The switch is then disabled once the system supply voltage rises above a certain threshold, which is set by the user. The reset voltage level varies depending on the type of reset circuit used. The reset voltage level is monitored by the circuit, and when it exceeds the threshold level, the reset circuit is activated.

The ADM1186-2ARQZ also features an integrated voltage regulator, enabling the device to power itself and other devices during the reset process. The voltage regulator also ensures that the output voltage is maintained within a certain range, even if the system supply voltage fluctuates. Additionally, it has an under-voltage and over-current detection circuit in order to protect the system from damage caused by excessive voltages.

In summary, the ADM1186-2ARQZ is a low-power supervisor from the PMIC category of electronic components, which is suitable for use in a wide range of applications. It provides a wide range of reset voltages and is equipped with an integrated voltage regulator, undervoltage and over current protection circuit for improved system performance.
