Power management integrated circuit (PMIC) supervisors are an important class of devices that provide a wide range of integrated power management solutions. The S-80133CNPF-JKSTFU is a member of this family of devices, offering a variety of power and protection functions. In this article, we will discuss the application field of the S-80133CNPF-JKSTFU and its working principle.

The S-80133CNPF-JKSTFU is a cost effective power management integrated circuit supervisor, which provides over-temperature protection, 6-V to 15-V input voltage range, precision voltage monitoring and adjustable reset timing. It is suitable for use in a variety of industrial and consumer applications, including automotive and communications. This device offers maximum protection to extend the life of devices in the application system.

The S-80133CNPF-JKSTFU is a combination of a supervisory and a reset circuit, with an optional watchdog function. The supervisory circuit monitors the power supply voltage and will reset the system if the voltage drops below a certain level. The reset circuit provides an output to activate a reset signal in the system if the power supply voltage drops below the reset threshold. The watchdog timer allows the system to be regularly reset to avoid stalling.

The supervisory circuit in the S-80133CNPF-JKSTFU uses a comparator to monitor the voltage level. This voltage is compared to an internal reference voltage generated from the IC bandgap reference. When the external voltage is lower than the internal reference, the device pulses the reset output. It also has an over-temperature protection circuit, which monitors the temperature of the device and follows an independent voltage reference.

The reset output of the S-80133CNPF-JKSTFU can be configured to activate a reset signal in the host system when the power supply voltage drops below the specified level. The user can also configure the timing for the reset, such as the time for the reset signal to be applied and the time for the reset signal to be deactivated. It can be used to ensure a robust system reset, either in case of a power failure or when the system is rebooted.

The optional watchdog function in the S-80133CNPF-JKSTFU monitors active system activity and triggers a reset if activity does not occur within the specified period of time. This is useful for detecting and correcting system errors that would otherwise cause the system to stall or fail. It also prevents the system from being reprogrammed with an inappropriate firmware version.

The S-80133CNPF-JKSTFU is a versatile power management integrated circuit supervisor that is suitable for use in a variety of applications. It offers a range of features, including adjustable reset timing, over-temperature protection, and an optional watchdog timer. This makes it an ideal choice for systems that require reliable power management and protection.
