Introduction

The S-80954CLPF-G7QTFG is a smart Power Management IC (PMIC) Supervisors, as there are multiple power management and control functions integrated into a single package. A PMIC Supervisors is a concerned device must monitor and control power in any application configuration, whether it is a single processor or multiple applications in multiple processor architectures. With the help of the S-80954CLPF-G7QTFG PMIC supervisors, the power management functions desired in the system can be achieved by providing a host of features. This article will discuss the features of the S-80954CLPF-G7QTFG PMIC supervisors, the related application fields and the working principle of S-80954CLPF-G7QTFG.

Features of S-80954CLPF-G7QTFG PMIC Supervisors

The S-80954CLPF-G7QTFG provides protection for circuits that operate from batteries, such as mobile phone or notebook computers. The S-80954CLPF-G7QTFG’s features include wide voltage operation range (1.1V to 6.5V), a voltage monitoring function with an adjustable voltage-up detection threshold and adjustable voltage-down detection threshold, a low-power shutdown and a low-current start-up function, an adjustable power-on reset output delay and a power-off reset output delay, a single-ended bidirectional ESD protection a reset valid over voltage protection and a watchdog timeout monitor.With these multiple features, the S-80954CLPF-G7QTFG PMIC supervisor can be used for different application fields.

Application Fields

The S-80954CLPF-G7QTFG PMIC supervisor is suitable for different application fields. With its adjustable voltage-down and voltage-up detection threshold, the S-80954CLPF-G7QTFG can be used for protecting battery systems, especially for mobile phones or laptop computers. It is also suitable for handheld devices, such as PDAs. For automotive applications, the S-80954CLPF-G7QTFG can be used for controlling system standby, such as monitoring the voltage level when the car is in idle mode. The low-power shutdown and low-current start-up function of the S-80954CLPF-G7QTFG is also suitable for automotive applications, as it can provide protection in case of a power failure. Furthermore, the S-80954CLPF-G7QTFG is also suitable for digital systems, such as routers, switches, network interface cards and printers, as it can provide protection against power surges. It also has single-ended bidirectional ESD protection and reset valid over voltage protection to provide reliable and efficient protection for digital systems.

Working Principle

The S-80954CLPF-G7QTFG PMIC supervisor is a voltage supervisor which is used to detect any type of current or voltage irregularities that can damage the circuitry or system. The working principle of the S-80954CLPF-G7QTFG is based on the fact that it monitors the voltage level at all its input/output terminals. It constantly checks the voltage level and when it is outside the operating range (1.1V to 6.5V), the S-80954CLPF-G7QTFG will shut down the system to prevent any damage. It can also be used to reset the system if it is continuously outside the operating range. In addition to monitoring and controlling the power, the S-80954CLPF-G7QTFG also provides a watchdog timeout monitor. The watchdog timeout monitor will periodically detect if any task is not running and then reset the system to restart it safely.

Conclusion

The S-80954CLPF-G7QTFG is a powerful and versatile PMIC supervisors. It provides multiple features, such as a voltage monitoring function with adjustable voltage-up and voltage-down detection thresholds, a low-power shutdown and low-current start-up function, a single-ended bidirectional ESD protection and a watchdog timeout monitor, to keep the system running safely. The S-80954CLPF-G7QTFG is suitable for battery systems, handheld devices, automotive applications and digital systems. The working principle of the S-80954CLPF-G7QTFG PMIC supervisors is based on monitoring the voltage level and resetting the system if it is out of the operating range.
