TPS22811x Load Switch Texas Instruments TPS22811x Load Switch is a highly-integrated, power-distribution solution in a small package. The device allows control and monitoring of power supply rails using a minimum number of external components. Output slew rate and inrush current can be adjusted using one external capacitor. Loads are protected from input overvoltage conditions by cutting off the output if the input exceeds an adjustable overvoltage threshold. The device integrates a fast-trip response to protect against severe faults at the output during steady-state.
