2.5 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.
2.6 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.
2.7 Open Load Detection
Open load is detected by current measurement in the High-Side switches during ON-
condition. If the output current drops below an internally fixed level (open circuit detection
current) the error flag is set with a delay.
2.8 Status Flag
The status flag outputs are open drain outputs with Zener-diodes which require pull-up
resistors, c.f. the application circuit on Page 16. Various errors as listed in the table
“Diagnosis” are detected by switching the open drain outputs ST1 or ST2 to low.
