Notes
• The current range given above represents conditions when output voltage is not in the avalanche state.
• If the output voltage is in the avalanche state, see the allowable avalanche energy for STK672-6** series hybrid ICs given
in a separate document.
• The operating substrate temperature, Tc, given above is measured while the motor is operating.
• Because Tc varies depending on the ambient temperature, Ta, the value of IOH, and the continuous or intermittent
operation of IOH, always verify this value using an actual set.
• The Tc temperature should be checked in the center of the metal surface of the product package.
