Patent ID: 7580236

Claim:
A device ( 1 ) for controlling several inductive loads ( 111 , 112 ), characterized in that it includes: at least one first group of several control stages ( 321 , 322 ) each having: a bonding pad ( 331 , 332 ) for an inductive load ( 321 , 322 ); a receive input ( 301 , 302 ) for a conduction activate signal; a switch ( 121 , 122 ) including a control electrode connected to the receive input, and an output electrode connected to the bonding pad; an enabling circuit ( 181 , 182 ), measuring the voltage applied to the bonding pad ( 331 , 332 ) and generating an enabling signal when this voltage reaches an enabling level; a conduction re-activate circuit ( 2 ) common to the control stages of the group, limiting the voltage on the bonding pad of the control stages of the group to a common level that is higher than the enabling level of each control stage of the group and applying a conduction activate signal to the control electrode for the switch of one of the control stages when the enabling circuit of this control stage generates an enabling signal.
