7.4.11 Output Short-to-Ground Protection

The device TLV61290 works in hiccup mode when output short-to-ground. The scheme of output short-to-ground protection (OSGP) is same as the scheme in start-up phase.

When output is short, the TLV61290 enters into hiccup mode. Once the overcurrent or short-circuit is released, the TLV61290 goes through the soft start-up again to regulated the output voltage.

The hiccup protection mode is disabled using I2C.
