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]
