DRIVER CHIP FOR DRIVING AN INDUCTIVE LOAD AND MODULE HAVING A DRIVER CHIP |
摘要 |
A driver chip for driving an inductive load and a module having a driver chip are provided. The driver chip contains a first transistor for coupling a first potential to a first output and a second transistor for coupling a second potential to the first output. A first protection circuit reduces an increased voltage between a control terminal and a load junction terminal of the first transistor. The driver chip has a first state in which the second transistor is turned off and the first transistor can switch a passive inductive load connected to the output. In a second state, the first transistor and the second transistor can switch an external power transistor connected to the first output. A second output is connected to a load junction terminal of the external power transistor. A second protection circuit reduces an increased voltage between the first and second outputs.
