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
• 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 I OH , and the continuous or intermittent
in a separate document.
operation of I OH , always verify this value using an actual set.
