PMIC, or power management integrated circuit, is a type of integrated circuit with the specific purpose of efficiently delivering, controlling, and regulating power to multiple electrical devices. Supervisors are special types of PMICs designed to provide power supply fault protection for microprocessors and/or memory systems. The S-80148ALPF-JA9TFG is an example of a PMIC supervisor that provides voltage monitoring, reset generation, and other features, making it suitable a variety of applications.

The S-80148ALPF-JA9TFG is a CMOS transistor-transistor logic based 8-bit micro-controller supervisor that is typically available in a surface mount PDIP-14 package. It operates with a supply voltage of between 2.2V and 6.5V, and has a maximum operating temperature of 85°C.

The S-80148ALPF-JA9TFG is designed to detect problems in the power supply system and initiate corrective action. It can detect an undervoltage condition, an overvoltage condition, an excessive current condition, and a power supply failure condition. When the supervisor detects any of these conditions, it can generate an alert signal, issue an on-chip reset, or execute an on-chip interrupt request.

The S-80148ALPF-JA9TFG is designed for use in microprocessor- and/or memory-based systems, and is especially suited for automotive and industrial applications. This supervisor can be used in application such as motor vehicle engine control, HVAC control, industrial process control, and most other industrial applications that require precise control over power supply fault conditions.

The S-80148ALPF-JA9TFG employs an on-chip voltage-monitoring feature that continuously monitors the system power supply voltage and generates an alert signal if the voltage is low, too high, or falls outside a predetermined range. This feature ensures that the power supply remains within the recommended parameters and thereby precludes problems such as unpredictable component behavior, system downtime, and component damage.

The S-80148ALPF-JA9TFG also features integrated reset generation logic, which initializes all the microprocessor or memory system components to a known initial state. This reset generation logic is activated in the presence of the specified conditions, such as an undervoltage, overvoltage, or power supply failure condition.

In addition, the S-80148ALPF-JA9TFG incorporates an integrated watchdog timer. This timer monitors system operation and generates a reset signal if the system does not complete a cycle within a certain amount of time. This ensures that the system does not stay stuck in an endless loop and that correct operations resume if a problem occurs.

Finally, the S-80148ALPF-JA9TFG includes an on-chip interrupt feature that can be activated in the presence of a power supply fault condition. This interrupt can be used to signal the microprocessor or memory system of a power supply fault, which allows the system to take corrective action quickly and effectively.

Overall, the S-80148ALPF-JA9TFG is an excellent example of a PMIC supervisor, suitable for use in a variety of automotive and industrial applications. It combines efficient voltage monitoring, reset generation, and inter-erupt capabilities into a single IC package, making it a great choice for applications that require precise power supply fault management.
