Recommended Operating Conditions
For proper operation the device should be used within the recommended conditions.
† Care should be taken to avoid output switching conditions where the V
S
node flies inductively below
ground by more than 5V.
Absolute Maximum Ratings
Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur. All
voltage parameters are absolute voltages referenced to COM. The thermal resistance and power
dissipation ratings are measured under board mounted and still air conditions.
