MAX14607 Overvoltage Protectors with Reverse Bias Blocking

Product Details

The MAX14606/MAX14607 overvoltage protection devices feature low 54mΩ (typ) on-resistance (R_ON) internal FETs and protect low-voltage systems against voltage faults up to +36V. When the input voltage exceeds the overvoltage threshold, the internal FET is turned off to prevent damage to the protected components.

The devices automatically choose the accurate internal trip thresholds. The internal OVLO are preset to typical 5.87V (MAX14606) or 6.8V (MAX14607).

The MAX14606/MAX14607 feature reverse bias blocking capability. Unlike other overvoltage protectors, when the MAX14606/MAX14607 are disabled, the voltage applied to OUT does not feed back into IN. These devices also feature thermal shutdown to protect against overcurrent events.

The MAX14606/MAX14607 are specified over the extended -40°C to +85°C temperature range, and are available in 9-bump WLP packages.
