CamSemi Launches Two New Controllers with Extra Protection for Smartphone Batteries

CamSemi announced specific variants of its recently launched C2173 and C2174 fast start Primary Side Sensing controllers to comply with an additional battery protection requirement that is being increasingly specified by smart phone handset manufacturers. The new C2175 and C2176 controllers include an intelligent foldback feature, offering output under voltage protection and target low cost MoU-compliant, USB smartphone chargers and other universal input applications rated at 8 W and 10 W respectively. This additional protection feature within the two variants is activated when a fault within the handset's normal charging routine or with one of its battery cells causes the output voltage to fall below 60% of its specified value. The controller shuts down the charger before issuing regular restart pulses to maintain its fast-start performance. The pulses either restart the normal charge cycle or incrementally charge the battery to a 3 V threshold before normal charging can continue. The new C2175 and C2176 PSS controllers offer smartphone charger manufacturers all the same features, cost and performance benefits as the company’s other C2170 controllers targeting higher power applications including: more efficient switching of bipolar transistors to deliver significant margins on the higher operating efficiencies required by DoE level 6 regulations. Five star (less than 30 mW) no-load power (NLP) performance, also with significant margin and fast-start charging without needing an active start-up switch. An integrated output transient detection feature can be used to help manufacturers further reduce NLP while maintaining fast transient response. C2175 is packaged in SOT23-6, C2176 in SOP8 and samples of both controllers are available now.
