The TPS206x power-distribution switches are intended for applications where heavy capacitive loads and short-circuits are likely to be encountered. This device incorporates 70-mΩ N-channel MOSFET power switches for power-distribution systems that require single or dual power switches in a single package. Each switch is controlled by a logic enable input. Gate drive is provided by an internal charge pump designed to control the power-switch rise times and fall times to minimize current surges during switching. The charge pump requires noexternal components and allows operation from supplies as low as 2.7 V. When the output load exceeds the current-limit threshold or a short is present, the device limits the output current to a safe level by switching into a constant-current mode, pulling the overcurrent (OCx) logic output low. When continuous heavy overloads and short-circuits increase the power dissipation in the switch, causing the junction temperature to rise, a thermal protection circuit shuts off the switch to prevent damage. Recovery from a thermal shutdown is automatic once the device has cooled sufficiently. Internal circuitry ensures that the switch remains off until valid input voltage is present. Current limit is typically 2.1 A.

TPS20xxC 和 TPS20xxC-2 配电开关系列产品用于诸如 USB 等有可能遇到高电容负载和短路的应用。 这一系列产品为电流介于 0.5A 和 2A 之间的应用提供具有固定电流限值阀值的多种器件。当输出负载超过电流限值阀值时，TPS20xxC 和 TPS20xxC-2 通过运行在恒定电流模式下来将输出电流限制在安全的水平上。 这就在所有条件下提供了一个可预计的故障电流。 当输出被短接时，快速过载响应时间减轻了主 5V 电源提供稳压电源的负担。 为了大大减少打开和关闭期间的电流冲击，电源开关的上升和下降次数受到控制。

TPS2069D

1.5A loading, 4.5-5.5V, 76mΩ USB power switch, active-high, output discharge, reverse blocking; • Single Power Switch Family\n• Rated currents of 1.5 A\n• ±20% Accurate, Fixed, Constant Current Limit\n• Fast Overcurrent Response: 2 µs\n• Deglitched Fault Reporting\n• Output Discharge\n• Reverse Current Blocking\n• Built-in Soft Start\n• Ambient Temperature Range: –40°C to 85°C\n• UL Listed and CB-File No. E169910;

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.
