Overvoltage Protectors Use Reverse Bias Blocking

Maxim Integrated Products Inc. announced the MAX14606/MAX14607, advanced overvoltage protectors which handle up to 3A of continuous current for today's high-power electronics. Reverse bias blocking protects a portable device from damage caused by multiple power sources supplied simultaneously. The MAX14606/MAX14607 are optimized to protect the internal components of portable electronics such as tablets, smartphones, and portable media players.

The MAX14606/MAX14607 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. Without this reverse bias blocking, users are forced to use multiple discrete, space-consuming external components to protect the end equipment.

To support today's demanding high-power portable devices, the MAX14606/MAX14607 also use low, 54mohm (typical) on-resistance, RDS(ON), 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 small 1.3mm x 1.3mm WLP package, the MAX14606/MAX14607 make electronics more robust and save the space required by discrete protection solutions.
