PMIC - Supervisors

PMIC, or Power Management Integrated Circuit, is an electronic IC designed to regulate and manage the power requirements of electrical devices. This is achieved by controlling and regulating the current, voltage, and frequency of the devices that require power. Supervisors are one type of PMIC, and these are utilized for precise power monitoring and control of microprocessors and other integrated circuits.

MAX6382XR28D3+T Application Field

The MAX6382XR28D3+T is a dual-channel, low-voltage, always-on supervisor IC from Maxim Integrated. This supervisor primarily monitors the power supply voltage levels and the state of reset signals of microprocessors and detects any irregularities that might indicate a power system fault. In addition to the power monitoring, the device also provides over-temperature shutdown and reverse battery protection to ensure reliable operation in harsh environments.The MAX6382XR28D3+T is used in a wide variety of applications, including embedded systems, automotive equipment, and industrial automation. It is particularly well suited for use in battery-operated devices as it offers superior battery protection features. Additionally, its small 8-pin SOIC package makes it easy to integrate with existing designs.

Working Principle

The MAX6382XR28D3+T has two independent power supply voltage monitor channels. Each channel can monitor a single power supply voltage level or two levels with the addition of an external resistor. Both channels provide a high accuracy power supply voltage monitoring capability with a high threshold accuracy of ±1%.Once the power supply voltage reaches the user-programmable threshold level, the supervisor IC will generate a reset signal. This reset then triggers the system to automatically go into a safe state, ensure against data corruption and protect the system from further harm.The MAX6382XR28D3+T also offers the ability to monitor temperature, which can be set to user-programmable trip points and is essential for reliable operation in harsh environments. The device also provides reverse battery protection and can detect when the battery is connected in reverse and shut down the system.Lastly, the MAX6382XR28D3+T also offers Active voltage and current monitoring capabilities which allows it to continuously monitor the power supply voltage and current in order to detect any irregular current surges or drops. With this monitoring capability, laptop manufacturers can ensure superior battery life and performance without the need of precise external voltage limiting devices.

Conclusion

The MAX6382XR28D3+T is an excellent choice for applications that require precise power monitoring and control. It allows users to monitor a variety of different power supply levels, detect anomalies, and also provides superior protection features such as over-temperature shutdown and reverse battery protection. With its excellent suitability for battery-operated applications, small form factor, and reliable performance, the MAX6382XR28D3+T is the perfect choice for those looking for a high performance power management supervisor.
