NOTES:

10. Refer to Safe Operating Area in Figure 8 and thermal design guidelines in AN2010.

11. Does not include margin limits.

12. Percentage of Full Scale (FS) with temperature compensation applied.

13. The device requires a delay period following an enable signal and prior to ramping its output. Precise timing mode limits this delay period to approx

2ms, where in normal mode it may vary up to 4ms.

14. Precise ramp timing mode is only valid when using EN pin to enable the device rather than PMBus enable. Precise ramp timing mode is automatically

disabled for a self-enabled device (EN pin tied high).

15. The devices may require up to a 4ms delay following the assertion of the enable signal (normal mode) or following the

17. Factory default is the initial value in firmware. The value can be changed via PMBus commands.

20. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.

Boldface limits apply over the operating temperature range, -40°C to +85°C.
