Overcurrent protection (I
If the voltage of the DC-link current exceeds the internal reference voltage, the commutation signals
are forced Low. Overcurrent protection is disabled after every carrier period.
Reference voltage = 0.5 V (typ.)
Gate block protection (RES pin)
When the RES input is High, the commutation outputs are disabled. When the RES input is then set
Low or open, the commutation outputs are re-enabled.
Any irregular conditions of the motor should be detected by external hardware; such indications
should be presented to the RES input.
(When RES = High, charging of the bootstrap capacitor stops. In case the operation re-starts by
deactivating reset, the bootstrap capacitor is not charged.)
Internal protection
Abnormal position signal protection
When the position signal inputs (UVW) are all Highs or all Lows, the commutation outputs are
forced off (i.e., set Low). When these inputs are then set to any other combination, the commutation
outputs are re-enabled. (The all-High and all-Low conditions are Hall sensor outputs.)
Undervoltage lockout (V
While the power supply voltage is outside the rated range during power-on or power-off, the
commutation outputs are set to the high-impedance state to prevent external power elements from
damage due to short-circuits.
