• Medical devices
• Communications systems

The MIC2594-1YM Hot Swap Controllers is a practical solution for designers and product engineers looking for a reliable, cost-effective solution for protecting their equipment from potential damage and downtime caused by power surges, short circuits, and over-voltage.

Working Principle

The MIC2594-1YM Hot Swap Controllers are built with an internal start-up circuit and a configurable, controlled power-MOSFET switch. The start-up circuit monitors the hot swap-controller\'s operating voltage, then turns on the power-MOSFET switch once the voltage reaches the configured threshold. The power-MOSFET switch is designed to provide fast, smooth turn-on and turn-off response times.In order to protect against over-current and short-circuit conditions, the MIC2594-1YM Hot Swap Controllers are equipped with an externally configurable, user-definable circuit protection. This includes adjustable, programmable over-current protection, as well as an adjustable, programmable open-drain circuit protection.For further protection, MIC2594-1YM controllers also feature an adjustable, programmable thermal shutdown circuit. This circuit is active when the controller\'s temperature exceeds the maximum operating temperature, or when the temperature rises too fast. The MIC2594-1YM controllers also feature an adjustable, programmable current limit circuit. This circuit is designed to protect against over-current loading and protect other equipment from damage.

Conclusion

In conclusion, the MIC2594-1YM Hot Swap Controllers from Micrel, Inc. are reliable and cost-effective solutions for protecting a variety of different electronics and equipment from potential over-current and short circuit conditions. These Hot Swap Controllers feature fast, smooth turn-on and turn-off times, adjustable, programmable over-current protection, an adjustable, programmable open-drain circuit protection, an adjustable, programmable thermal shutdown circuit, and an adjustable, programmable current limit circuit. As such, these controllers provide designers and product engineers with a reliable and cost-effective solution for protecting their equipment from potential damage and unnecessary downtime.
