SLVUBX8B October 2020 – December 2021 TPS2661
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.
| Part Number | EVM Function | Channel | IN Range | Overload Response | Application |
|---|---|---|---|---|---|
| TPS2661EVM Evaluation Board | Current input protection on CH1, analog output protection and sensor supply protection on CH2 |
CH1 – TPS26610 | Current input range: ±20 mA | Depends on MODE pin selection. See Section 8.4 in the data sheet for the details | Analog input protection for current inputs |
| CH2 – TPS26612 | Voltage input range: 0 to +Vs | Analog module output port protection |
TVS diodes U6 and U7 are required when burden resistor (R8–R11) is floating, jumpers J17 and J19 are open (burden resistor is not connected to GND).
