PRODUCTION DATA
When the output is off, the output is pulled down to GND if a load is connected. But if an open load occurs, the output voltage is close to the supply voltage (VVS – VOUT < V(ol,off)), and the device recognizes an open-load fault.
There is always a leakage current I(ol,off) on the output due to the internal logic control path or external humidity, corrosion, and so forth. As a result, TI recommends using an external pullup resistor to offset the leakage current when an open load is detected. The recommended pullup resistance is 15 kΩ.
