When users connect their devices to fast chargers via a USB cable, hackers may be able to compromise the charger by sourcing more power than the device can safely handle, damaging or even destroying the device. Fast chargers and power supplies designed with Dialog’s Rapid Charge™ controllers cannot be hacked, because they are hard-wired state machines, so there is no firmware that can be accessed and corrupted. And, with a hard-wired state machine, you won’t need to spend extra time and expense to harden firmware or add overload protections.
