2 Description

The TPS25980EVM eFuse Evaluation Board enables evaluation of TPS259804O eFuse from TPS25980x

family. The input power is applied between connectors J1 and J3 while J2 and J5 provides the output

connection to the load; refer to the schematic in Figure 1, and EVM test setup in Figure 2. D1/C1 provides

input protection for the TPS259804O eFuse while D2/C2 provides output protection.

S1 allows U1 to be RESET or disabled. A power good (PG) indicator is provided by D3. Scaled device

current can be monitored at TP15 with a scale factor of 0.13 V/A.

In this user guide, the test procedure is described for TPS259804O device. Following similar test steps,

TPS259802O/3O/7O variants from TPS25980x family can also be evaluated.

Make sure the evaluation board has default jumper settings as shown in Table 6.

Figure 2. TPS25980EVM Setup with Test Equipment

Follow these instructions before starting any test and repeat again before moving to next test:

• Set the power supply output (VIN) to zero volts.

• Turn ON the power supply and set the power supply output (VIN) to 12 V, current limit = 20 A.

• Turn OFF the power supply.

• Set the jumper setting on EVM to default position as shown in Table 6.

Test Setup and Procedures

SLUUCB4–June 2020

TPS25980EVM: Evaluation Module for TPS25980x efuse

5.1 Hot-Plug Test

Use the following instructions to measure the inrush current during Hot-Plug event:

1. For checking inrush current control capability, insert additional capacitance of 1800 uF at C16

terminals. Total output capacitance = 1800 uF + 220 uF ~2 mF.

2. Set Jumper J12 in 3-4 position to set Cdvdt at 10 nF for o/p slew rate of 0.5 V/ms.

3. Set the input supply voltage VIN to 12 V and current limit of 5 A. Enable the power supply.

4. Hot-plug the supply between input connectors J1 and J3.

5. Observe the waveform at VOUT (TP2) with an oscilloscope to measure the slew rate and rise time of

the eFuse with a given input voltage of 12 V.

Figure 3 shows an example of inrush current captured on the TPS25980EVM eFuse Evaluation Board.

5.2 Current Limit Test

Use the following instructions to perform current limit test:

1. Place jumper J9 in 3-4 Position to set 2 ms for ITIMER.

2. Set the input supply voltage VIN to 12 V and current limit of 15 A and enable the power supply.

3. Place jumper J10 in 7-8 Position to set 8 A current limit.

4. Set the electronic load to 6 A and connect between VOUT and GND. Enable the electronic load.

5. Now apply overload of 4 A (using resistive load of 3 Ohm) between VOUT and GND.

6. The device allows the overload current for the programmed ITIMER period for example, 2 ms and then

switches OFF.

7. Place jumper J10 at other settings to test at various current limits.

Figure 4 shows an example of current limit at 8 A on the TPS25980EVM eFuse Evaluation Board.

5.3 Output Hot-Short Test

Use the following instructions to perform output Hot-Short test:

1. Set the input supply voltage VIN to 12 V and current limit of 15 A. Turn ON the power supply.

2. Short the output of the device for example, VOUT to GND with a shorter cable.

3. Observe the waveforms using an oscilloscope.

5.4 Wakeup into Short Test

Use the following instructions to perform wakeup into short test:

1. Set the input supply voltage VIN to 12 V and current limit of 10 A. Turn OFF the power supply.

2. Short the output of the device for example, VOUT to GND with a shorter cable.

3. Turn ON the power supply.
