- The alarm function can ensure safe and efficient and fast charging without using an AD converter -
Ablic Inc., Minebeamitsumi Inc.)) S-82L1/T1/U1/V1 series single-section battery protection IC with alarm function.
The new series of S-82L1/T1/U1/V1 released today can accurately detect when the battery voltage reaches the alarm threshold to achieve simple and safe fast charging without the need for AD converter.Specifically, there are the following characteristics:
(1) The detection accuracy of the battery voltage is as high as ± 12mV, and the alarm signal is output.Even if the voltage difference is influenced by the voltage difference caused by the detection resistance or the charging and discharge control FET drive during fast charging, the battery voltage is accurately detected.(The characteristics of the entire series.), (2) the industry's top -level over -charging detection voltage, the accuracy is ± 12mv (the characteristics of the entire series.), (3) the industry's top charging/discharge over current detection voltage accuracy is ± 0.75MV can inhibit changes in current detection, while reducing the detection flow resistance (S-82V1 series).
Due to the above characteristics, battery voltage can be accurately detected even in fast charging to ensure safe and efficient and fast charging. At the same time, high -precision overcharging detection is achieved, which greatly improves the safety of the product.This series is the upgrade of the S-82Y1B and S-82S1/R1 series. The complete product lineup can meet the customer's demand for fast charging.
