PMIC – Hot Swap Controllers

A hot swap controller is a type of power management integrated circuit (PMIC) that allows a device to be connected or disconnected while power is still flowing. Hot swap controllers are used in many applications, from basic devices such as computers and medical equipment to more specialized applications such as aerospace, military and automotive. One example of a hot swap controller is the MIC2585-1LBTS from Micrel, Inc.

MIC2585-1LBTS Overview

The MIC2585-1LBTS is a high-efficiency, low-voltage, dual-channel hot swap controller. It provides both over-current protection (OCP) and over-voltage protection (OVP) while regulating output voltage during the hot swap process. In addition, it can handle voltage levels up to 5.5V, making it ideal for a wide range of applications. Other features include an independent power-up control signal and analog control inputs for specific application requirements.

MIC2585-1LBTS Application Field

The MIC2585-1LBTS is suitable for use in a wide range of applications, such as computers, telecommunications, automotive, aerospace and industrial. Its low-voltage, high-efficiency operation makes it an ideal choice for applications that require power regulation during hot swapping. In addition, its wide OVP and OCP protection ranges make it suitable for a variety of voltages and currents in different applications.

Working Principle of MIC2585-1LBTS

The MIC2585-1LBTS hot swap controller works by monitoring the voltage of the input line, and providing an output signal depending on the detected voltage levels. When the input voltage is below the OVP threshold, an output signal is provided to switch off the connected device. Similarly, when the input voltage is above the OVP threshold, the output signal is switched off, disconnecting the device from the power supply and preventing any damage due to possible over-voltage conditions.

The MIC2585-1LBTS also provides over-current protection. When the line current exceeds the set threshold for the OCP, the controller triggers the OCP circuitry to switch off the connected device, thus preventing any potential damage due to current overloads.

Conclusion

The MIC2585-1LBTS from Micrel, Inc. is a dual-channel hot swap controller designed for a range of applications in telecommunications, automotive, aerospace and industrial applications. Its high-efficiency, low-voltage operation and wide OVP and OCP protection ranges make it suitable for a variety of voltages and currents in different applications. In addition, it provides an independent power-up control signal and analog control inputs for specific application requirements.
