MIC2585-1KBTS

Power Management Integrated Circuit (PMIC) devices enable power management functions integrated into a single chip, providing efficient centralized power control system, reducing development time and cost to designers. Hot Swap Controllers are an essential part of PMIC devices, providing a safe way to insert and extract equipment from a live power source. The MIC2585-1KBTS hot swap controller is an advanced switching PWM controller that offers seamless live insertion and removal of high current bus transceivers with low power loss.

The MIC2585-1KBTS is a single-chip hot swap controller designed to support dual port, side-by-side and stack-side type systems. It works by controlling the voltage and current at the board edges of the power source, thus providing a smooth and safe power up sequence. The device is capable of providing up to 4.5A of continuous output current. The MIC2585-1KBTS features over-current protection, thermal shutdown and soft-start protection, as well as a programmable current limit for system protection. The device also includes a built-in surge-suppression circuit, which utilizes a snubber network to limit the input spike caused by external capacitors. This device also supports up to 12V input voltages.

The MIC2585-1KBTS has a single circuit configuration, which allows for simplified layout and easy scalability. The main applications for this hot swap controller are in power systems with multiple high current devices, such as data centers, routers and switches. The device offers protection and high efficiency with a low quiescent current design. The MIC2585-1KBTS can also be used in low-voltage systems, such as LED lighting and consumer electronics, where the power source needs to be monitored and regulated.

In terms of working principles, the MIC2585-1KBTS is designed to start up slowly when current is applied, providing a soft-start feature that limits inrush current and protects the system and load. The controller operates in a constant-current mode, and will automatically reduce the out port voltage when the load current exceeds the current limit. The MIC2585-1KBTS also protects the system from over-voltage and over-temperature conditions, by monitoring the junction temperature and providing a programmable thermal shutdown function.

Overall, due to its flexibility and high efficiency, the MIC2585-1KBTS is an ideal choice for designers who are looking for an advanced hot swap controller that provides superior protection, flexibility and scalability for their applications. Its unique design allows for easy implementation and monitoring of multiple high current devices. Whether it is used in a data center, router, or consumer electronics application, the MIC2585-1KBTS can help provide a safe and efficient power source.
