Derating Curve of Motor Current, IOH, vs. STK672-410 Operating Substrate Temperature, Tc

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 STK672-4** 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.
