Power Management Integrated Circuits (PMICs) are a type of integrated circuit (IC) commonly used in many different kinds of devices. They provide the power needed to help ensure safe and reliable operation of devices. One type of PMIC is the Supervisory, which fulfill important power management tasks, such as monitoring voltage levels, triggering and resetting systems, and protecting circuits from damage due to excessive voltage or current.

The MIC6315-29D2U TR is a 3V supervisor with two independent windowed voltage detection circuits. It is designed to detect a power supply valid or logic level input and generate an active-low reset pulse if the voltage goes above or below a predetermined window. The window is set via external resistors, allowing for easy control of the voltage reset threshold. The MIC6315-29D2U TR contains two independent push-pull outputs to initiate two separate reset actions. This supervisor also has a power-on reset output, low supply current, and fast response time, making it ideal for many different applications.

The MIC6315-29D2U TR is widely used in automotive, industrial, and communications applications. In automotive applications, it is commonly used to reset power management systems, brakes, and clutches. In industrial applications, it is often used to reset industrial machines to prevent damage due to excessive heat or pressure. In communications applications, the MIC6315-29D2U TR can be used in resetting the baseband processor and radio systems. It is often used in combination with analog and digital power switching systems.

The MIC6315-29D2U TR functions by detecting an input voltage, comparing it to the set window, and then resetting the system if the input voltage is either too high or too low. This process is known as windowed voltage detection. The MIC6315-29D2U TR operates in two independent states: Mode 1 and Mode 2. In Mode 1, the device can be configured to monitor one voltage threshold from an analog or digital power supply. In Mode 2, the device can be configured to monitor two voltage thresholds from two separate power supplies.

The MIC6315-29D2U TR supplies two independent push-pull reset outputs: RESET1 and RESET2. RESET1 is used when Mode 1 is enabled, while RESET2 is used when Mode 2 is enabled. When the input voltage is above or below the predetermined window, one of the reset outputs will go active, signaling that the system must be reset. Additionally, the MIC6315-29D2U TR has a power-on reset (POR) output, which is generated when the device is initially powered up.

In summary, the MIC6315-29D2U TR is a 3V supervisory with two independent windowed voltage detection circuits, which is suitable for many different applications. It is designed to detect an input voltage and compare it to the set window, and then reset the system if the voltage is either too high or too low via two separate reset outputs. Additionally, the device also has a power-on reset feature to ensure a safe power up. The MIC6315-29D2U TR is widely used in automotive, industrial, and communications applications.
