NOTES:
4. Current in VCC5 is actually higher disabled, due to extra current required to pull down against the FS_DIS pin. VCC12 current is lower disabled.
5. Guaranteed by design, not production tested. Exceeding the maximum current from PVCC5 may result in degraded performance and unsafe
operation.
6. Guaranteed by design, not production tested.
Electrical Specifications
Recommended Operating Conditions, unless otherwise noted. VCC12 = 12V
Temperature = 0 to +70°C (typical = +25°C) for Commercial; Temperature = -40 to + 85°C (typical = +25°C) for
Industrial. Refer to Block Diagram, Simplified Power System Diagram, and Typical Application Schematic.
