2 Description

The TPS48111Q1EVM evaluation board enables evaluation of TPS48111-Q1 driver from TPS4811x-Q1 family. 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 3-1 and EVM test setup in Figure 5-1.

D4 and D5 provide the fault indication output for the overcurrent and overtemperature faults respectively. Scaled current of the load can be monitored at TP10.
