4.1 Schematics

The EVM schematic is shown in Figure 4-1.

TPS1685EVM TPS1685EVMFuse Evaluation Board Schematic Figure 4-1 TPS1685EVMFuse Evaluation Board Schematic
Note:
  • To evaluate the performance of one TPS1685 eFuse at lower currents (andlt; 20A), R36, R41, R46, R48, R49, and R51 resistors need to be depopulated, and R37 and R42 resistors must be populated to disable the secondary eFuse.
  • The ground connections for the various components around the TPS1685 eFuses must be wired directly to each other and the GND pins of respective eFuses. This must be followed by connecting them to the system ground at one point, as implemented using R8 and R50 resistors in the EVM schematic. Do not connect the various component grounds through the high current system ground line.
