使能端高电平有效、具有输出放电功能的 1.5A、4.5V 至 5.5V、76mΩ USB 电源开关 5-SOT-23 -40 to 125
The TPS2069D power-distribution switch family is intended for applications such as USB where heavy capacitive loads and short circuits are likely to be encountered. The device can continuously deliver up to 1.5 A output current.
The TPS2069D limits the output current to a safe level by operating in a constant-current mode when the output load exceeds the current limit threshold. This provides a predictable fault current under all conditions. The fast overload response time eases the burden on the main 5-V supply to provide regulated power when the output is shorted. The power-switch rise and fall times are controlled to minimize current surges during turnon and turnoff.
