Power management integrated circuits (PMICs) are a type of integrated circuit (IC) designed to include several power management circuits on a single chip. PMICs are used in almost all portable electronic products such as smartphones, tablets, laptops and even wearable devices. They are also used in industrial, automotive and military applications. PMICs are divided into different categories based on their applications, such as voltage regulators and Supervisors.

Supervisors are the most popular type of PMICs, as they combine high performance and low power consumption in a small package. Supervisors are designed to provide power management, monitoring and protection features, making them ideal for a variety of applications. The S-80845CLY-B2-U is a popular supervisor IC manufactured by Toshiba Corporation.
