Power management ICs (PMICs) are integrated circuits that monitor, control and regulate power within a device. Supervisors, one of the main components of PMICs, are designed to monitor and maintain critical system signals, including supply voltage, supply current, reset and power-up/power-down sequences. The S-80825CNPF-B8KTFG is one such supervisor, designed to control the power supply system in a wide range of applications.

The S-80825CNPF-B8KTFG includes components such as a low dropout (LDO) linear regulator and an n-channel power MOSFET for high current load. Together, these components allow for efficient power management and provide the designer with an unprecedented level of flexibility and reliability. With a wide input voltage range, the S-80825CNPF-B8KTFG also eliminates the need for a discrete circuit which can add cost and complexity to the design.

The S-80825CNPF-B8KTFG is designed for use in a variety of applications, including microprocessor and microcontroller power, memory and logic power, system power, and supply voltage monitoring. Its low quiescent current, and its ability to remain active even after it has been disabled, make it especially useful in low power applications and battery powered designs. Additionally, with its integrated low dropout linear regulator, the S-80825CNPF-B8KTFG is also capable of handling larger device current requirements.

The S-80825CNPF-B8KTFG employs a number of features designed to ensure reliable and efficient power delivery. It can monitor supply voltages within the range of 0.8 to 5V and has a slew rate accuracy of 0.5%. An adjustable supply voltage comparator monitors the supply voltage and triggers an interrupt if there is an out-of-tolerance power delivery condition. Additionally, a user adjustable digital reset detector can detect a reset caused by either a power-on reset or a manual reset.

The S-80825CNPF-B8KTFG provides an adjustable programmable delay timer that can be used to control the reset duration. This timer can be used to extend the timeout of a power-on reset or to create a delayed power-on reset to ensure that the power supply system is in a stable state before the main processor is enabled. Additionally, the S-80825CNPF-B8KTFG includes low voltage reset and brownout functionality to reduce power supply disruption, as well as programmable hysteresis for improved stability.

The S-80825CNPF-B8KTFG also includes an adjustable voltage alarm circuit to monitor the supply voltage and detect out-of-tolerance power delivery conditions. This circuit can be used to issue warnings or interrupts when the system is out of control. Finally, an autostart circuit is also included, allowing the device to start itself when the power supply is enabled.

In summary, the S-80825CNPF-B8KTFG is an ideal supervisor solution for applications where stringent voltage and current regulation are required. Its wide input voltage range, low quiescent current, and integrated features make it a cost-effective and reliable option for power management applications.
