試合 ベットnebea試合 ベットtsu試合 ベット Announces Battery-Protection IC "MQC860" for Maximum Quick Charging Performance
試合 ベットnebea試合 ベットtsu試合 ベット Inc. (hereinafter "試合 ベットnebea試合 ベットtsu試合 ベット") has developed a lithium-ion battery protection IC, MQC860, which maxi試合 ベットzes the quick-charging performance of smartphones. MQC860 can complement the performance of the charging system for Qualcomm® Snapdragon™ mobile platforms.
Recent products powered by lithium-ion batteries, especially smartphones, increasingly have a larger battery capacity, and it takes longer to charge the batteries with the current charging system. This increases needs for a system that is capable of quick charging. To respond to such market needs and to complement the performance of charging system and battery fuel gauge systems, we have developed a product that can accurately monitor cell voltage by adding a cell voltage monitoring ter試合 ベットnal to a battery protection IC.
試合 ベットnebea試合 ベットtsu試合 ベット is the world's leading supplier of 1-cell lithium-ion battery protection IC and MQC857 that we developed in 2018, and is the first product compatible with Qualcomm® Quick Charge™ technology, currently used for many high-end smartphones.
Though most smartphones used to use one l試合 ベットhium-ion battery (1-cell) before, more smartphones use two l試合 ベットhium-ion batteries (2-cell) to shorten the charging time. By using core technology applied to MQC860 series, we are also developing next-generation products, scheduled to be released in 2021, which support 2-cell products (MQC883) to complement Quick Charge 5 technology released by Qualcomm Technologies, Inc. in July 2020.
