DC1496C-A，基于具有 I2C 接口的 LTC2941 電池電量計的演示板

使用 Analog Devices 的 LTC2942IDCB 的參考設計

設計簡介

DC1496C-A 演示電路采用 LTC2941，這是一款電池電量監測計，可測量電池充電和放電、電池電壓和芯片溫度。該器件測量手持式 PC 和便攜式產品應用中的電池充電狀態。該演示板包括一個外部 100 m-Ohm（默認）檢測電阻，用于最大電流測量 500mA（±50mV 電流檢測電壓范圍）。 2.7V 至 5.5V 工作范圍非常適合單節鋰離子電池。三個測量量（電荷、電壓和溫度）存儲在可通過板載 SMBus/I2C 接口訪問的內部寄存器中

說明

DC1496C-A, Demonstration Circuit features the LTC2941, a battery gas gauge that measures battery charge and discharge, battery voltage and chip temperature. This device measure battery charge state in handheld PC and portable product applications. The demo board includes an external 100 m-Ohm (default) sense resistor for a maximum current measurement of 500mA (±50mV current sense voltage range). The 2.7V to 5.5V operating range is perfectly suited for single cell Li-Ion batteries. The three measured quantities (charge, voltage and temperature) are stored in internal registers accessible via the on-board SMBus/I2C interface
