Introduction

MAX792SCSE is a Microprocessor Supervisor from the MAXIM Company, which is a popular supplier of integrated circuit solutions. It belongs to the classification of PMIC or Power Management ICs, which are widely used to monitor, manage, and control the power supply of a system or component. MAX792SCSE is a type of Supervisor IC that is specifically designed for controlling and monitoring the power supply for microprocessors, also known as Supervisors.

Applications

The MAX792SCSE is a 4-pin, low-power Supervisor IC. It is widely used in applications such as systems on chip (SoC), low-power green computing, desktop and embedded computers, base stations, set-top boxes, and power supplies. In addition, the MAX792SCSE is suitable for applications where low-power and leakage current are important. This is because the device has an ultra-low power consumption of only 3 µA and a low device leakage of only 30 nA.The MAX792SCSE comes in a space-saving, miniaturized package and is also available in a two-pack, which eliminates the need for an additional supervisor IC package on the PCB. Furthermore, it is compatible with single-cell and multicell battery-powered applications.

Operating modes and features

The MAX792SCSE has various operating modes, which enable it to adapt to different environments and applications. These operating modes include the Active Mode, Sleep Mode, Standby Mode, and Hibernate Mode.The Active Mode is when the MAX792SCSE is in its most active state. In this mode, it is actively monitoring and controlling the power supply of the system.The Sleep Mode is a low-power mode and is used when the MAX792SCSE is not in use. This mode consumes much less power than the Active Mode and can be used to reduce battery consumption.The Standby Mode is a mode that the MAX792SCSE enters after being in the Sleep Mode for a certain period of time. In this mode, the MAX792SCSE powers down the system until it is ready to be used again.The Hibernate Mode is the state the MAX792SCSE enters when the system needs to power down entirely. In this mode, the MAX792SCSE completely shuts down the system and only powers back on when needed. The MAX792SCSE also incorporates a comparator function, which it uses to monitor the system’s supply voltage. If the voltage falls below a pre-set threshold, the MAX792SCSE will initiate a reset and restart the system’s power supply.

Working Principle

The MAX792SCSE works by monitoring the system’s supply voltage and initiating a reset if the voltage falls below a pre-set threshold. It also automatically enters one of its four operating modes depending on the system’s activity.When the system is in the Active Mode, the MAX792SCSE is constantly monitoring and controlling the power supply of the system. It is also monitoring the comparator function, which it uses to detect if the supply voltage falls below a pre-set threshold.In the Sleep Mode, the MAX792SCSE is not actively monitoring or controlling the power supply. However, it is still monitoring the comparator function. In the Standby Mode, the MAX792SCSE remains in a low power state and is monitoring the comparator function.In the Hibernate Mode, the MAX792SCSE is completely powered down and is not actively monitoring anything.

Conclusion

The MAX792SCSE is an ultra-low power Supervisor IC from MAXIM Company that is designed for controlling and monitoring the power supply of microprocessors. It is used in applications such as systems on chip (SoCs), low-power green computing, desktop and embedded computers, base stations, set-top boxes, and power supplies. It has various operating modes, which enable it to adapt to different environments and applications. Furthermore, it incorporates a comparator function, which it uses to monitor the system’s supply voltage. The MAX792SCSE works by monitoring the system’s supply voltage and initiating a reset if the voltage falls below a pre-set threshold.
