The S-80135ALPF-JAUTFG is a highly advanced power management integrated circuit (PMIC) that is a part of a family of supervisors released by SMD. These supervisors provide a cost-effective way to protect microprocessor-based systems against problems caused by overvoltage, overtemperature, inrush current, reset time-out, and system supply failure. The S-80135ALPF-JAUTFG was developed to provide protection for advanced electronic systems that are being used in a wide range of applications from high-end computing to automotive or communications equipment.

S-80135ALPF-JAUTFG can be used in a wide range of applications, for example, providing protection for microprocessor-based systems against overvoltage, overtemperature, inrush current, reset time-out, and system supply failure. This device is also used to provide intelligent power management for always-on systems, providing the optimal balance between system performance and power utilization. It is also suitable for use in 5V to 24V DC power supply systems, and can be used to monitor multiple power rails.

The S-80135ALPF-JAUTFG features a wide power-up threshold range, extendable reset time-out, inrush current threshold, and overvoltage, overtemperature, and system supply failure protection. It also provides a wide operating temperature range, and its Low-Voltage VL-mode allows for the protection of systems with supply voltages as low as 1.8V. It also has an automatic reset monitoring system that detects any potential problems before it leads to system failure.

The working principle of the S-80135ALPF-JAUTFG is based on voltage supervisor and comparison circuits. This supervisor circuit is the core of the programmable power management function of the PMIC. The voltage supervisor circuit contains a reference voltage, comparators, and a reset circuit that monitor the system voltage. The reference voltage is adjustable, and the comparator will detect a low or high voltage. The reset circuit is reset automatically when a fault condition is detected.

The S-80135ALPF-JAUTFG also features a power management section which consists of a power-up sequencing circuit, soft start circuitry, and a power-down sequencing circuit. The power-up sequencing circuit monitors the system power and the output voltage, and allows for an adjustable start cycle to be programmed. The soft start circuitry can be used to reduce the inrush current when the system is powered up, and the power-down sequencing circuit is used to power down the system in an orderly manner.

Overall, the S-80135ALPF-JAUTFG is a highly advanced PMIC designed for a wide range of applications. It provides overvoltage, overtemperature, inrush current, reset time-out, and system supply failure protection. It is also suitable for use in 5V to 24V DC power supply systems, and can be used to monitor multiple power rails. In addition, it has an adjustable power-up, soft start, and power-down sequencing circuitry that can be programmed and controlled as needed.
