Notes
1. V_CCA12, V_CCV12, V_CCS12 and V_CC5 are connected together; the outputs SDRVU, SDRVV, SDRVW, V_CMP and V_CMN
are not loaded. Sleep mode defined by 000 as spindle code and VCM disable.
2. Switching levels with respect to SDRVU, SDRVV and SDRVW.
3. For the description of the Power-on reset see Fig.6.
4. On spindle motor drivers:
a) Zero duty factor guarantees zero current output.
b) 5% duty factor guarantees current output.
c) Maximum current will be activated at 100% duty factor.
5. 0.2 V < V_SDRVN < V_CCA12 − 1 V.
