The MAX14670–MAX14673 provide protection to valuable consumer circuits against positive voltage faults up to +28VDC. An internal clamp also protects the devices from surges up to +100V. The device is able to disconnect the system from its output terminal when wrong input conditions are detected.
The MAX14670–MAX14673 overvoltage protection devices feature low 65mΩ (typ), WLP package on-resistance (RON) internal FETs, effectively minimizing the voltage drop across the device. When the input voltage exceeds the overvoltage threshold, the internal FET is turned off to prevent damage to the protected components.
The overvoltage protection threshold can be adjusted with optional external resistors to any voltage between 5V and 22V. The devices automatically choose the accurate internal trip thresholds when the overvoltage lockout input (OVLO) is set lower than the external OVLO select voltage. The internal OVLO are preset to typical 6.8V (MAX14670), 15.5V (MAX14671), 5.825V (MAX14672), or 22V (MAX14673).
The MAX14670–MAX14673 feature reverse bias blocking capability. Unlike other overvoltage protectors, when the MAX14670–MAX14673 are disabled, the voltage applied to OUT does not feed back into IN. These devices also feature an OTG enable pin that allows OUT voltage to supply IN. The MAX14670–MAX14673 also have thermal shutdown protection against over load conditions.
The MAX14670–MAX14673 are specified over the extended -40°C to +85°C temperature range. The MAX14670/MAX14671 are available in a 15-bump WLP package and the MAX14672/MAX14673 are available in a 10-pin TDFN package.
