BQ26231 的說明

The bq26231 is a low-cost charge/discharge counter peripheral in an 8-pin TSSOP. It works with an intelligent host controller, providing state-of-charge information for rechargeable Li-Ion, Li-Pol, or NiMH batteries. The bq26231 measures the voltage drop across a low-value series sense resistor between the negative terminal of the battery and the battery pack ground contact. By using the accumulated counts in the charge, discharge, and self-discharge registers, an intelligent host controller can determine battery state-of-charge information. To improve accuracy, an offset count register is available. The system host controller is responsible for the register maintenance by resetting the charge in/out and self-discharge registers as needed.

The bq26231 features 13 bytes of registers, which contain the capacity monitoring and status information. The RBI input operates from an external power storage source such as a capacitor or a series cell in the battery pack, providing register nonvolatility for periods when the battery is shorted to ground or when the battery charge state is not sufficient to operate the bq26231. During this mode, the register backup current is less than 100 nA. Packaged in an 8-pin TSSOP, the bq26231 is small enough to fit in the crevice between two A-size cells or within the width of a prismatic cell.

包裝類型選項

您可依零件數量選擇不同包裝類型選項,包含完整捲盤、客製化捲盤、剪切捲帶、承載管或盤。

客製化捲盤是從一個捲盤上剪切下來的連續剪切捲帶,以維持批次和日期代碼可追溯性,依要求剪切至確切數量。依照業界標準,銅墊片會在剪切捲帶兩側連接 18 英吋前後導帶,以直接送至自動組裝機器。針對客製化捲盤訂單,TI 將酌收捲帶封裝費用。

剪切捲帶是從捲盤剪切下來的一段捲帶。TI 可能使用多條剪切捲帶或承載盒,以滿足訂單要求數量。

TI 常以盒裝或管裝、盤裝方式運送承載管裝置,視現有庫存而定。所有捲帶、管或樣本盒之封裝,皆符合公司內部靜電放電與防潮保護包裝要求。
