PMIC stands for Power Management Integrated Circuit and are the devices used in the power management system for the maximum efficiency of energy output. The multi-functionality of these circuits is the result of the integrated on-chip components and provides an integrated solution which helps in reducing overall power consumption and increasing the time available to perform a specific operation. ADM1813-10AKS-REEL is one such active device, designed by Analog Devices, which provides supervisory and system reset functions.

The ADM1813-10AKS-REEL protects the system from any potentially dangerous situation due to under-voltage or over-voltage conditions. It helps in maintaining the system in a healthy operating mode by monitoring two supply voltages, VCC and VDD. This integrated circuit has an adjustable undervoltage lockout voltage and programmable delay so that it can be tuned with the global specifics of a system. It also features positive and negative going output transistor to eliminate the wrong reset assertion that may occur during reset timeout period.

ADM1813-10AKS-REEL application field encompasses a wide range of embedded systems such as consumer electronics, autos, telecommunication and many more. With its wide operating temperature range it can be used even in harsh climate. Its high integration of components and wide figure of merit like supply current, low voltage, etc., makes it suitable for power-sensitive applications. This device meets the PQFN 6x6 packaging specifications and a maximum continuous operating temperature of -40ºC to +125ºC.

The typical working principle of ADM1813-10AKS-REEL is to monitor and control VCC, VDD load supply above pre-specified single reference voltage. It continuously monitors these two supply voltages. During normal operation both the voltage supplies should be above pre-specified level otherwise false reset will occur. If any of these two voltages falls below the pre-specified voltage level, a reset is asserted. To avoid any false reset conditions the triggering of reset is controlled by the configurable reset timeout and UVLO (Under Voltage Lock Out). The reset will be removed automatically or manually when the VCC and VDD supply reflects that it is back to a healthy state.

In conclusion, ADM1813-10AKS-REEL is a highly integrated, single device with wide application fields and offers extended operating temperature range, easy to configure features and low power consumption. This PMIC - Supervisors is designed with flexible configuration options to suit a wide variety of applications.
