Failures or faults in today’s smart device power adapters can cause an overvoltage event, as can hot-plugging an adapter into the power input of a mobile device.
With the prevalence of universal connectors, a user can also unknowingly plug in the wrong adapter, damaging the device with a high or even negative power supply voltage. Analog Devices LTC4360, LTC4361, and LTC4362 products can protect against these fault situations with minimal components. Read this article for a comparison of the three devices.
