Microchip Technology, Inc. PMIC - Hot Swap Controllers MIC2583-LBQS-TR

The MIC2583-LBQS-TR is a single-channel hot swap controller designed for safe insertion of boards into live system backplanes. It operates within a supply voltage range of 2.3V to 13.2V and provides surge voltage protection up to 20V. The device features programmable inrush current limiting, ensuring controlled current flow regardless of load capacitance, and includes an electronic circuit breaker that latches off the output MOSFET in case of excessive load faults. The MIC2583-LBQS-TR responds quickly to short-circuit conditions, with a response time of less than 1µs, and offers undervoltage lockout (UVLO) protection. It also includes power-on-reset (POR) and power-good (PG) status outputs, enhancing system reliability. The device is suitable for applications such as RAID systems, base stations, and network switches, making it a versatile choice for engineers looking to implement hot swap functionality in their designs.
