OVER-VOLTAGE PROTECTION
path regulator will be turned off immediately, by opening M1 and M2, while M3 gets closed. When the over-voltage condition
disappears for longer than the debounce time, charging will resume and previously programmed SPI settings will be reloaded.
An interrupt CHGFAULTI is generated with associated CHGFAULTM mask bit with the CHGFAULTS[1:0] bits set to 01.
state machine. As a result, for over-voltage conditions of up to 30 μs, the charger state machine may not always end up in the
over-voltage fault state, and therefore an interrupt may not always be generated.
over-voltage is detected the internal circuitry of the USB block is disconnected. A USBOVI is generated in this case. For more
details see Connectivity.
guaranteed. If the user wants to protect against these failure conditions, additional protection will be required.

In order to protect the application, the voltage at the CHRGRAW pin is monitored. When crossing the threshold, the charge
In order to ensure immediate protection, the control of M1, M2, and M3 occurs real-time, so asynchronously to the charger
The VBUS pin is also protected against over-voltages. This will occur at much lower levels for CHRGRAW. When a VBUS
When the maximum voltage of the IC is exceeded, damage will occur to the IC and the state of M1 and M2 cannot be
Excludes spread and tolerances due to board routing and 100 mOhm sense resistor tolerances.
An additional derating of 35% is allowed.
This condition applies when using an external charger with a 3.0 m long cable.
