2 Description

The TPS22811EVM load switch Evaluation Board has one channel and enables 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. Refer to the schematic in Figure 3-1 and EVM test setup in Figure 5-1. TVS diode D2 provides input protection from transient overvoltages, while Schottky diode D12 provides output protection for the TPS22811 load switch.

S2 allows U1 to be RESET or disabled.
