Patent ID: 7002309

Claim:
A power window driving apparatus, comprising: a reference current generator, which generates a reference current having a level corresponding to a motor current which flows to a power window driving motor, the reference current generator including: a first current generator, which generates a first current having a level corresponding to a variation level of the motor current, a first comparison signal converted from the first current, and a second comparison signal also converted from the first current; a reference voltage generator, which generates a reference voltage signal based on a time mean value of the second comparison signal; and a second current generator, which generates a second current which has a level corresponding to the reference voltage signal, and the second current being equal in level to the reference current when added to the first current; a comparator, which compares the first comparison signal with the reference voltage signal; a driving controller, which stops or reverses the driving motor when it is determined that a drastic increase is occur in the motor current based on a result of a comparison by the comparator; and a current increaser, which increases an amount of the second current for a predetermined period when the motor current is drastically decreased from a steady state, so that an increase in the first current is suppressed when the motor current is shifted from the drastically decrease to an increase.
