Note:
  • To evaluate the performance of TPS1689 at lower currents (<20A), R83, R85, R73, R88, R87 and R82resistors need to be depopulated, and R81 and R84 resistors must be populated to disable the secondary eFuse (TPS1685).
  • The ground connections for the various components around the TPS1689 and TPS1685 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 RZ1 and RZ4 resistors in the EVM schematic. Do not connect the various component grounds through the high current system ground line.
