Power management integrated circuit (PMIC) in modern electronics is an essential component found in a wide range of applications. PMICs are used to provide the required voltage, current, and power supply for various integrated circuits (ICs). A popular type of PMIC is supervisors, which are used to ensure that electronic systems operate within safe operating conditions and can be reset or power-cycled when necessary. The S-80821CNPF-B8GTFU is a Supervisor from Sanken Electric, Japan, and is a great example of the PMIC – Supervisors form factor.

S-80821CNPF-B8GTFU Application Field

The S-80821CNPF-B8GTFU is a power-on reset IC that is typically used in microcontroller (MCU) and digital signal processor (DSP) applications. This IC ensures that the MCU or DSP starts up correctly and restores them to safe operating conditions in the event of unexpected faults or other events that can lead to data corruption or system instability. The IC is used to supplant or replace expensive and complex external logic with a cost-effective and flexible IC solution.

One of the unique aspects of the S-80821CNPF-B8GTFU is that it offers shutdown and power-on management independent of the system processor. This means that the IC can be used to handle complex power-on management scenarios without relying on the processor to perform the necessary calculations and calculations. This feature is especially useful in applications where an MCU is expected to be turned off and back on frequently, such as industrial automation.

The S-80821CNPF-B8GTFU can also be used in digital televisions (DTVs) and computer peripherals as a means of detecting and providing power to the system components. Digital TVs often have multiple systems and peripherals that require power, and the S-80821CNPF-B8GTFU can detect the presence of each of these components and turn on the necessary power rails. This helps to prevent excessive current draw that could cause damage to the system. It also helps to reduce power consumption when not in use.

S-80821CNPF-B8GTFU Working Principle

The S-80821CNPF-B8GTFU works by detecting an overvoltage and undervoltage condition on two distinct pins and the internal regulator, while monitoring the start-up voltage. When the monitored voltage drops below the over-voltage threshold, the S-80821CNPF-B8GTFU will shut down and go into a low power state. When the monitored voltage rises above the over-voltage threshold, the S-80821CNPF-B8GTFU willpowers up the system and provide a reset pulse.

The S-80821CNPF-B8GTFU also has a fail-safe feature that prevents it from attempting to turn on the system again when an under-voltage condition is detected. This helps to prevent damage to the system components from excessive power draw. The S-80821CNPF-B8GTFU can also be configured to trigger an interrupt for systems that require power failure notification.

The S-80821CNPF-B8GTFU is a low-power and cost-efficient solution for managing power-on reset and power-off conditions. This IC makes it possible to reduce the complexity and costs associated with custom power management solutions while offering the reliability and flexibility that designers need. This allows designers to create smarter and more affordable solutions that better meet the needs of their customers.
