Threshold of current limiting diagram

The I2C bus register that is set for default to "habilitation" enables the step up. In case of

14V operation or split supply the step-up and no i2c bus mode the step-up is disabled by

connects the BSTVSense pin to a reference of at least five volts over VSM.

During the testing phase the digital test mode is entered by put Csense pin at least 3V under

14V pin.
