Overvoltage protectors use reverse bias blocking for multiple power sources
The chips feature reverse bias blocking capability so that two power sources can be safely interfaced simultaneously without damage to either one. In this design two integrated back-to-back FETs prevent the voltage applied at the intended output from feeding back into the input, removing the need for multiple discrete, space-consuming external components. The ICs also use low, 54mΩ (typical) on-resistance, integrated FETs that allow up to 3A of continuous current and protect low-voltage systems against voltage faults up to +36V. With all of these features in a 1.3×1.3mm WLP package, the MAX14606/MAX14607 make electronics more robust and save the space required by discrete protection solutions.
