RT5712B
Over-Current Protection (OCP)
The RT5712B provides over-current protection by
detecting low side MOSFET valley inductor current. If
the sensed valley inductor current is over the current
limit threshold (2.9A typ.), the OCP will be triggered.
When OCP is tripped, the RT5712B will keep the
over-current threshold level until the over current
condition is removed.
Thermal Shutdown (OTP)
The device implements an internal thermal shutdown
function when the junction temperature exceeds 150°C.
The thermal shutdown forces the device to stop
switching when the junction temperature exceeds the
thermal shutdown threshold. Once the die temperature
decreases below the hysteresis of 20°C, the device
reinstates the power up sequence.
