Power Management Integrated Circuit (PMIC) - Hot Swap controllers provide a mechanism for safely and reliably connecting and disconnecting power rails from a system. This is used in many applications such as systems with digital logic or analog devices, circuits ranging from low power LED controllers up to high power motors, digital communication interfaces, and medical devices. The MIC2583R-JBQS-TR is a hot swap controller developed by Microchip Technology specifically for hot swap applications. The MIC2583R-JBQS-TR is a low-power, low-vibration, low-current hot swap controller that offers a variety of features, including programmable identification, current limit, and timer settings. In this article, we will discuss the application field and working principle of the MIC2583R-JBQS-TR.

Application Field

The MIC2583R-JBQS-TR provides the necessary protection for hot swap applications such as memory modules and other cards that can be added to a system in a live environment. The MIC2583R-JBQS-TR also offers important protection features that help ensure the safe and reliable operation of a system. These features include over-voltage protection for hot swap boards, a programmable current limit, and over-temperature protection.

The MIC2583R-JBQS-TR has a wide operating temperature range of -40⁰C to +85⁰C and supports both 3.3V and 5V logic levels. It also features an integrated low noise linear regulator, an integrated charge pump, and an active-high logic interface. These features make the MIC2583R-JBQS-TR an ideal choice for applications that require a reliable hot swap controller.

Working Principle

The MIC2583R-JBQS-TR consists of an over current limit threshold, a safety timer, and an active high logic interface. The over-current limit threshold is used to detect when the current draw of the system exceeds a predetermined threshold, thereby signaling the need for power disconnection from the system. The safety timer is used to set a delay time for the disconnection in order to avoid any potentially damaging currents.

The active-high logic interface is used to control the hot swap controller. It consists of three pins (VCC, Enable, and Fault) that are used to control the hot swap controller. The VCC pin is used to supply the device with power, the Enable pin is used to trigger the power disconnection when the over-current limit threshold is exceeded, and the Fault pin is used to indicate a fault condition. The Fault pin is asserted low when the over-current limit threshold is exceeded or when the safety timer times out.

The MIC2583R-JBQS-TR also features programmable current limit, voltage limit, and temperature limit settings. The current limit setting is used to ensure that excessive current draw does not occur in the system, while the voltage limit setting is used to protect the device from over-voltage conditions. The temperature limit setting is used to protect the device from over-temperature conditions. All of these settings can be programmed in software, allowing for the hot swap controller to be customized for a variety of applications.

Conclusion

The MIC2583R-JBQS-TR is a low-power, low-vibration, low-current hot swap controller developed by Microchip Technology specifically for hot swap applications. It features a variety of features, including programmable identification, current limit, and timer settings. It also features an integrated low noise linear regulator, an integrated charge pump, and an active-high logic interface. The MIC2583R-JBQS-TR is an ideal choice for applications that require a reliable hot swap controller.
