Under-Voltage-Lockout (UVLO)

When VS reaches the switch-on voltage VUV ON the IC becomes active with a hysteresis.

The High-Side output transistors are switched off if the supply voltage VS drops below

the switch off value VUV OFF.

Over-Voltage-Lockout (OVLO)

When VS reaches the switch-off voltage VOV OFF the High-Side output transistors are

switched off with a hysteresis. The IC becomes active if the supply voltage VS drops

below the switch-on value VOV ON.

Open Load Detection

Open load is detected by current measurement. If the output current drops below an

internal fixed level the error flag is set with a delay.

Status Flag

Various errors as listed in the table “Diagnosis” are detected by switching the open drain

outputs ST1 or ST2 to low.
