Power management integrated circuits (PMICs) are devices that monitor and control the voltage and current supply of the system. Supervisor devices are a type of PMICs, a subset focused on providing the system with information on power-on status and reset signals. By providing a discreet signal when system power is applied and when a predefined condition has been met, supervisor devices provide the system with increased control and reliability. One of the most popular supervisor devices is the S-80922CNPF-G8STFG, which features many of the latest developments in supervisor device technology.

The S-80922CNPF-G8STFG is designed to detect power up or down conditions on a single or multiple power rails, making it very useful in a wide range of applications. The device can be used to monitor power supplies, detect power loss or power up events, and detect over-voltage or over-current conditions. It can also be used to control external power relays or other power-related components, such as in a hot-swap application.

When used as a power-on supervisor (POS), the S-80922CNPF-G8STFG can be configured to assert a reset signal when power is applied to the system. It can also be configured to de-assert the reset signal when a predefined voltage is reached. This can be very useful in systems that require safe power-up sequences, as it can prevent the system from attempting to start without the necessary voltages in place. The device also has the ability to detect power down conditions, asserting an active low reset signal when power is removed from the system.

The S-80922CNPF-G8STFG supports various reset schemes and can be configured for either open-drain or push-pull reset output type. It also features non-volatile memory for retaining the reset configuration, which eliminates the need for external memory or complex programming operations. The device can detect voltages from 1.3V to 5.5V, with a maximum operating temperature range of -40°C to 125°C. It is available in 8-pin SOT-23 and DSBGA packages, with a wide range of compatible system power rails.

The S-80922CNPF-G8STFG also features an adjustable reset-valid delay, allowing it to provide precise timing control over the reset. This can be very useful in applications where precise conditions and intervals must be met in order to safely power up the system. Additionally, the device supports manual reset and push-button reset functionality, allowing the user to reset the system without the need for external commands.

In summary, the S-80922CNPF-G8STFG is a highly capable supervisor device, featuring the latest in PMIC technology for monitoring and controlling power systems. It is designed for a wide range of applications, from simple systems that require power supply monitoring to advanced systems that need precise power up or down timing control. With its adjustable reset valid delay, non-volatile memory, and wide range of compatible system power rails, the S-80922CNPF-G8STFG is an ideal choice for power management implementations.
