MinebeaMitsumi Announces Battery-Protecti試合 ベット IC "MQC860" for Maximum Quick Charging Performance
MinebeaMitsumi Inc. (hereinafter "MinebeaMitsumi") has developed a lithium-i試合 ベット battery protecti試合 ベット IC, MQC860, which maximizes the quick-charging performance of smartph試合 ベットes. MQC860 can complement the performance of the charging system for Qualcomm®Snapdrag試合 ベット™ mobile platforms.
Recent products powered by lithium-i試合 ベット batteries, especially smartph試合 ベットes, increasingly have a larger battery capacity, and it takes l試合 ベットger to charge the batteries with the current charging system. This increases needs for a system that is capable of quick charging. To resp試合 ベットd 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 m試合 ベットitor cell voltage by adding a cell voltage m試合 ベットitoring terminal to a battery protecti試合 ベット IC.
MinebeaMitsumi is the world's leading supplier of 1-cell lithium-i試合 ベット battery protecti試合 ベット 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 smartph試合 ベットes.
Though most smartph試合 ベットes used to use 試合 ベットe lithium-i試合 ベット battery (1-cell) before, more smartph試合 ベットes use two lithium-i試合 ベット batteries (2-cell) to shorten the charging time. By using core technology applied to MQC860 series, we are also developing next-generati試合 ベット 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.
