High Voltage Hot Swap Controllers

With operating voltages up to ±1000 V, Analog Devices’ high voltage hot swap controller ICs provide a rugged and reliable solution for critical, high availability −48 V (such as AdvancedTCA®) and +48 V systems in networking and telecommunications. Galvanic isolation protects low voltage digital circuits controlling high voltage supplies in industrial, datacom, electric vehicle, and avionics systems. Some of the controllers offer board power monitoring capabilities with integrated ADCs, accessible through an I2C/SMBus interface.
