Texas Instruments TPS22811EVM Load Switch Evaluation Module

Texas Instruments TPS22811EVM Load Switch Evaluation Module (EVM) allows reference circuit evaluation of the TPS22811 load switch. The TPS22811 device is a 2.7V to 16V, 10A load switch with integrated 6mΩ FET with inrush current protection, programmable under voltage and over voltage protection, current monitoring, and quick output discharge. The Texas Instruments TPS22811EVM has one channel and enables the evaluation of the TPS22811L load switch. Channel 1 is a standalone channel and provides programmable OVLO, dVdt, and IMON settings. The input power is applied at connector J9 while J14 provides the output connection. TVS diode (D2) provides input protection from transient overvoltages, while Schottky diode (D12) provides output protection for the TPS22811 load switch.

Features
