NOTES:

1. VCC_CORE must be applied to the OCVR input before OCVR_OK can become valid (even though it could be pulled high if the

VCC_SMB supply is turned on, see figure 41.

2. The OCVR_OK signal is not guaranteed to be valid until 0.5 mS (max) after Vin to the OCVR reaches 90% of it’s nominal value.

3. Vin is the input to the OCVR (VCC_CORE).

4. Vout is the output from the OCVR (VCC_CPU).
