HOT SWAPPABLE SUPERCAPACITOR BACKUP POWER CONTROLLER PROVIDES UNINTERRUPTED POWER, PROTECTION AND MONITORING

摘要

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 LTC335VS integrated hot swap controller and circuit breaker uses 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.
