Microchip Technology, Inc. Hot Swap Controllers MIC2595R-1YM-TR

The MIC2595R-1YM-TR is a single-channel, negative voltage hot swap controller designed for safe insertion and removal of circuit boards in live systems, specifically operating within a voltage range of -19V to -80V. It features a fast-responding circuit breaker that reacts to short circuit conditions in less than 1µs, along with user-programmable overcurrent detection response times. The device offers two circuit breaker functions: it can either latch the output off after a fault condition or automatically retry at a fixed duty cycle, depending on the configuration. This controller includes active current regulation to manage inrush currents and provides programmable undervoltage and overvoltage lockouts, as well as hysteresis settings. It also features staggered 'Power-Good' output signals for load sequencing, which can be configured as active-high or active-low. The MIC2595R-1YM-TR is suitable for applications in central office switching, -48V power distribution, and distributed power systems, making it a versatile choice for engineers looking to implement hot swap capabilities in their designs.
