active-semi® is providing a Family of eFuse products with active power loss protection and autonomous storage capacitor health monitoring. During a write cycles in SSDs it is important to detect an eminent power loss and actively signal this to the controller and allow a completion of data storage to not loose vital information. To ensure that the provided storage capacitors are capable of providing this function the ACT49xx products periodically conduct capacitor health screening.
