High-voltage, high-current overvoltage protectors focus on mobile applications with multiple power sources

March 07, 2012 // By Paul Buckley
Maxim Integrated Products Inc. has introduced the MAX14606/MAX14607, advanced overvoltage protectors which handle up to 3 A 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, 54 milliohms (typical) on-resistance (RON), integrated FETs that allow up to 3 A of continuous current and protect low-voltage systems against voltage faults up to +36 V. With all of these features in a small 1.3 mm x 1.3 mm WLP package, the MAX14606/MAX14607 make electronics more robust and save the space required by discrete protection solutions.

The MAX14606/MAX14607 are part of a broader family of high-voltage, high-current overvoltage protectors. For similar parts in this family, please go to Maxim’s Overvoltage Protection Controllers.
