Notes: 5. The device will shut down operating after the output current I O is over the output current limit I OM for 160us (typically). The device will re-start
up operating after resetting the supply voltage Vdd.
6. I n initial power on time, the output state is kept in “High” in this start-up time of IC.
7. Typical data is at T A =+25 °C, Vdd=24V and is design information only.
