The MAX14727/MAX14728/MAX14731 provide protection to valuable consumer circuits against two positive voltage faults up to +28VDC. An internal clamp also protects the devices from surges up to 100V. The devices automatically select the input source, with channel A being the primary supply.These devices feature reverse bias-blocking capabilities. Unlike other overvoltage protectors, when the devices are disabled, the voltage applied to OUT does not feed back into either INA or INB. These devices also feature two OTG enable pins (OTG_ENA, OTG_ENB) that allow OUT voltage to supply the corresponding input when OUT is higher than the output startup voltage.These overvoltage-protection devices feature high-voltage, low on-resistance (73mΩ, typ) internal FETs, effectively minimizing a 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 devices also have thermal-shutdown protection against overload conditions.The overvoltage-protection threshold can be adjusted with optional external resistors to any voltage between 4V and 14V. The devices automatically choose the appropriate internal trip thresholds when the overvoltage-lockout input is set lower than the external OVLO select voltage. The internal OVLO are preset to 13.75V (typ) (MAX14727), 10V (typ) (MAX14728), or 5.92V (typ) (MAX14731).The devices are specified over the extended -40°C to +85°C temperature range, and are available in a 30-bump, wafer-level package (WLP).Applicationse-ReadersSmartphonesTablets
