2.1 Setup

The TPS4800Q1EVM evaluation board enables evaluation of TPS48000-Q1 driver. The input power is applied between connectors J1 and J4 while J2 and J3 provide an output connection to the load, Refer to the schematic in Figure 5-1 and EVM test setup in Figure 4-1.

D4 provides the fault indication output for under-voltage fault, short-circuit fault and during SCP comparator diagnosis whereas D5 provides the fault indication output for gate drive UVLO.
