spindle motor pre-driver combination chip
TDA5149G
Table 13
Configuration of the six commutation states in hard-switching mode
Note
1.
2.
3.
H1, H2 and H3 are the upper power FETs connected to MOT1, MOT2 and MOT3 respectively.
L1, L2 and L3 are the lower power FETs connected to MOT1, MOT2 and MOT3 respectively.
INIT = 1 means ‘state 1’ situation with PWM stuck in OFF on L2.
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
