Texas Instruments bq76200 高侧 N 通道 FET 驱动器

Texas Instruments bq76200 高侧 N 通道 FET 驱动器是一款高电压电池组前端充放电驱动器。 高侧保护避免系统接地中断。 它们还能确保电池组与主机系统之间进行连续的通信。 该器件有一个额外的 P 通道 FET 控件，用于以低电流预充深度耗尽的电池，还有一个 PACK+ 主机电压监控器控件，用于感测 PACK+ 电压。 独立使能输入能够让 CHG 和 DSG FET 单独打开和关闭，为电池系统提供了更大的执行灵活性。 bq76200 器件可与模拟前段（bq76920/30/40 3 系列至 15 系列电池模拟前段监控）和主机微控制器或专用荷电状态 (SOC) 跟踪气体压力表器件共同使用。

The device has additional P-Channel FET control to allow low-current pre-charge to a deeply depleted battery, and a PACK+ voltage monitor control for the host to sense the PACK+ voltage. The independent enable inputs allow CHG and DSG FETs to be turned on and off separately, offering great implementation flexibility in battery systems. The bq76200 device can be used with a companion Analog Front End (bq76920/30/40 3-series to 15-series Cell Analog Front End Monitoring) and a host microcontroller or dedicated state-of-charge (SOC) tracking gas gauge device.
