Analog Devices announces the Power by Linear LTC3351, a supercapacitor charger and backup power controller IC that includes hot swap front-end protection and all the features necessary to provide a complete, standalone capacitor-based backup power solution. The LTC3351’s integrated hot swap controller and circuit breaker use N-channel MOSFETS to provide a low loss power path from the input to the output, plus foldback current limiting to reduce inrush current. The device enables reliable short term uninterrupted power in the event of a main power failure for applications such as solid-state drives (SSDs) and nonvolatile dual in-line memory modules (NVDIMMs) data backup, power fail alarms in medical and industrial applications and ‘dying gasp’ power fail indicators. The LTC3351 provides PowerPath
control, capacitor stack charging and balancing, protection and capacitor health monitoring. Other applications include high current 12V ride-through supplies and short term uninterruptible power supplies (UPS) for servers, mass storage and high availability systems. [via]
