Power transistor driving circuit |
摘要 |
A driving circuit is provided for a power transistor connected to an inductive load. A detection resistor is placed between ground and the emitter of the power transistor. The driving circuit has a first portion which is capable of generating a first current which is a non-linear function of the voltage across the detection resistance. A second portion of the driving circuit is used to generate a base current for the power transistor that is proportional to the first current. The non-linear function of the first current compensates for the non-linear gain with respect to collector current of the power transistor.
