2.1 Overview

The TPS4810Q1EVM evaluation board enables evaluation of TPS48100-Q1 driver. The input power is applied between connectors T1 and T4 while T2 and T3 provide an output connection to the load. Refer to the schematic in Figure 5-10 and EVM test setup in Figure 4-1.

D3 provides the fault indication output for under-voltage fault, charge pump UVLO, short-circuit fault and during SCP comparator diagnosis.
