the protection state. Using I

2C to shutdown the system

and then re-enable it will also unlatch UVP function. The

event is recorded in register 0x18.SCP. The record can

be reset with I

2C interface or automatically reset by re-

power-on AVDD.

VOUT

Over-Current Protection (OCP)

The converter senses the current signal when the high-

side P-MOSFET turns on. As a result, The OCP is cycle-

by-cycle current limitation. If the OCP occurs, the converter

holds off the next on pulse until inductor current drops

below the OCP limit. The event is recorded in register

0x18.OCP. The record can be reset with I2C interface or

automatically reset by re-power-on AVDD. The OCP level

can be set with 0x16.IPEAK[1:0].

Over-Temperature Protection (OTP)

The converter has an over-temperature protection. When

the junction temperature is higher than the thermal

shutdown rising threshold, the system will be latched and

the output voltage will no longer be regulated until the

junction temperature drops under the falling threshold.
