Hot-Swap and Load Switches

Hot Swap products from Analog Devices perform all the housekeeping functions necessary to hot swap plug-in boards. These parts also integrate with industry-leading converter and amplifier cores for power monitoring and control with patented circuitry delivering unmatched ± 3% monitoring accuracy. Hot swap controllers play a key role in keeping central office switching stations and server banks operating at peak efficiency. These devices safely and accurately monitor the power usage in a typical server rack system which enables operators to remotely monitor each rack individually thus saving energy and minimizing system downtimes.

Analog Devices offers a variety of hot swap controllers including shunt regulated, low and high side FET drivers optimized for -48 V systems. There are also I2C interface hot swap controllers that allow for digital voltage and current data to be read from the device and power consumption for the rail to be calculated.

Hot Swap evaluation software, design resources, tools, and online technical support can help shorten your design time. Designers can quickly select products based on key specifications with our Hot Swap parametric search tables. They can also exchange ideas and get free online design help through the Power Management Support Community on EngineerZone™.
