Texas Instruments TPS2661EVM, User Manual, Page: 3 / 32

2 Description
The TPS2661EVM evaluation board enables evaluation of TPS26610 and TPS26612 current loop protectors.
The input signal is applied between connectors J1 and J13 while J3 and J9 provides the output connection to the
load; see the schematic in
Figure 3-1 , and EVM test setup in Figure 5-1 . U1 in channel-1 provides current input
protection and U3 in channel-2 provides output analog output protection and sensor supply protection.
LEDs D1 (D5) provide visual indication when the device U1 (U3) operates outside normal operating conditions.
Table 2-1 details the eFuse options and settings.
