The S-80153BLPF-JFETFU is a highly advanced power management integrated circuit (PMIC) developed by Sanken Electric Co., Ltd. It is a supervisor type PMIC that provides a variety of power management functions and operations in personal computers, mobile phones, and other electronic and electrical products. This type of PMIC is also suitable for automotive, military, and other industrial application fields.

The S-80153BLPF-JFETFU integrates four linear regulators and one step down converter into a single 32-pin QFN package. The four linear regulators are P-Channel MOSFET output low drop-out regulators with adjustable output voltage range from 0.4V to 5.5V, which is suitable for regulating the input voltage of CMOS RAM, Non-Volatile EXternal Memory (NVER) and other digital devices. It also has an adjustable three-level step-down DC-DC converter to generate a stable 1.5V output, making it ideal for the power of low-noise acoustics, RF transceivers, gyroscopes and other sensitive peripheral devices.

The S-80153BLPF-JFETFU also includes a full suite of power control and power protection features, such as thermal shutdown, current-limit protection, short-circuit protection, over-voltage protection and under-voltage protection. It also includes power sequencing, which can be programmed to ensure the proper sequencing of multiple power supplies within a system. Furthermore, its power-saving modes can reduce current consumption in the system, prolonging the system’s runtime.

In addition, the S-80153BLPF-JFETFU offers high-speed start-up time with a range of operating temperature from -40℃ to 125℃. Moreover, its low power-on reset voltage and current-limit reset voltage make it ideal for a wide range of applications, including consumer electronics, handheld portable devices, embedded systems and automotive.

The working principle of the S-80153BLPF-JFETFU is based on the principle of controlling the output power based on the input voltage. The input voltage is regulated by an external voltage regulator or direct link with a power supply line. The circuit then adjusts the output voltage or current to the required level according to the input voltage variations. The power management functions can be programmed through the integrated analog-to-digital converters, allowing for adjustment of parameters such as output voltage, current, and thermal protection.

In summary, the S-80153BLPF-JFETFU is a highly advanced, supervisor type PMIC suitable for a wide range of applications, including consumer electronics, handheld electronic devices, embedded systems and automotive applications. It provides a variety of power management features and operations, such as adjustable linear regulators, adjustable three-level step-down converter, power sequencing, thermal shutdown, current-limit protection, short-circuit protection, over-voltage protection and under-voltage protection. Furthermore, its high-speed start-up time and wide range of operating temperatures make it suitable for use in a variety of environments.
