3 说明

TPS22976 产品系列包含三款器件：TPS22976、TPS22976A 和 TPS22976N。每款器件都是一个接通受控的双通道负载开关。此器件包含两个可在 0.6V 至 5.7V 输入电压范围内运行的 N 沟道 MOSFET，并且每通道可支持最大 6A 的持续电流。每个开关可由一个导通/关断输入（ON1 和 ON2）独立控制，此输入可与低压控制信号直接连接。TPS22976 能够在结温超出阈值时热关断，以此关断开关。开关会在结温稳定在安全范围内时再次导通。此外，TPS22976 还包含一个可选 230Ω 片上负载电阻，用于在此开关被关断时进行快速输出放电。

TPS22976 采用小型、节省空间的3mm × 2mm 14-SON (DPU) 封装，此类封装集成有散热焊盘，支持较高功耗。器件在自然通风环境下的额定运行温度范围为 –40°C 至 105℃。
