PMIC - Supervisors

PMIC, or Power Management IC, is a device that manages the power supply of a system. It is used in many different applications and the most common one is determining the working state of a circuit. Supervisors are a type of PMIC that specifically monitors the operating conditions of electronic systems. The MIC1815-20U-TR is one such supervisor.The MIC1815-20U-TR is a highly integrated voltage monitor, designed to protect hardware in low voltage systems. It is capable of monitoring multiple voltage rails and has active high and active low reset pins. It is designed to monitor multiple fully functional state of applications. Thanks to its highly sensitive comparator and timer, the MIC1815-20U-TR can accurately detect voltage levels, allowing it to precisely identify when a system has become operational. It also has several other features such as auto-purge polling and brown-out detection.The MIC1815-20U-TR is most often used in embedded systems, industrial control, medical systems, and automotive electronics. In embedded systems for instance, the device helps the system determine what power state it is in by measuring its power inputs. This information is then used to determine when to enter a sleep mode.In industrial controls, the MIC1815-20U-TR is used to monitor and control high current loads such as pumps and motors. The device can detect when the voltage is within a certain range and can switch between on and off states, making it an ideal solution for controlling high current loads in industrial settings. In medical systems, acceptable working conditions are often monitored using the MIC1815-20U-TR. This device can detect when the voltage deviates from the accepted range, alerting a medical staff to the change in voltage and prompting further tests or a corrective action.Finally, automotive electronics also benefit from the integration of the MIC1815-20U-TR. The device is used to monitor the voltage level of a car battery, alerting drivers to when their battery power is running low or needs to be replaced.In terms of operation, the MIC1815-20U-TR uses an internal voltage reference and comparator circuit to monitor the voltage level of its inputs. The device can be preset to trip and reset at prespecified points, and it has multiple enable (EN) and clear (CLR) pins, allowing for better integration and control over the circuitry. The device also provides flexibility to adjust the comparison lower threshold levels.Overall, the MIC1815-20U-TR is a versatile voltage monitor suitable for a wide range of applications. Its ability to offer both active high and active low reset pins make it a great choice for embedded, industrial, medical, and automotive electronics. Its internal voltage reference and comparator circuitry make it an ideal solution for monitoring voltage levels and ensuring reliable operation of any system.
