Maxim MAX1467x Overvoltage Protectors
Maxim MAX1467x Overvoltage Protectors provide protection to circuits against positive faults up to +28VDC. These devices feature a low 65mΩ (typ) and WLP package on-resistance (RON) internal FETs to effectively minimize 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. Designers can adjust the overvoltage protection threshold with optional external resistors to any voltage between 5V and 22V. The series also features a reverse bias blocking capability. Unlike other voltage regulators, when the MAX1467x device is disabled, the voltage applied to OUT does not feed back into IN. The over the extended -40°C to +85°C temperature range, makes the Maxim MAX1467x Overvoltage Protectors ideal for tablets, smart phones, E-readers, PC notebooks, and charging USB hosts.
