Texas Instruments TPS22968 双通道负载开关
德州仪器 TPS22968 双通道负载开关是一款小型、超低 RON、双通道负载开关，具有受控接通。该器件包含两个可在 0.8V 至 5.5V 输入电压范围内运行的 N 沟道 MOSFET，每通道可支持最高达 4A 的持续电流。每一开关可由一个打开/关闭输入（ON1 和 ON2）独立控制，此输入可直接对接低压控制信号。为能够在开关关闭时快速进行输出放电，TPS22968 中添加了一个 270Ω 的片上负载电阻器。TPS22968 采用小型、节省空间的封装 (DPU)，且集成了散热焊盘，支持较高的功率耗散。在自然通风环境下，该器件在 -40°C 到 85°C 的温度范围内额定运行。
特性
- Integrated dual channel load switch
- 0.8V to 5.5V Input voltage range
- 2.5V to 5.5V Ideal for 1S battery configuration VBIAS voltage range
- Ultra low RON resistance RON = 27mΩ at VIN = 5V (VBIAS = 5V)
