unit:mm (typ)

Derating curve of motor current, IOH, vs. 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 STK672-6** 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.
