Temperature stable circuit for controlled current discharge during the driving of an inductive load |
摘要 |
A circuit for controlled discharge of energy stored in an inductive load, comprising an active semiconductor device (T) connected serially with the inductive load (L) between first and second terminals of a voltage supply source and having a control terminal for connection to a driver circuit (C), and a control circuit (R1, R2, COMP) connected between the inductive load and said control terminal. The control circuit comprises a voltage divider (R1, R2) connected between the inductive load (L) and the first terminal of the voltage supply source, and a comparator (COMP) having first and second input terminals respectively connected to the voltage divider and to a voltage reference and an output terminal which is coupled to the control terminal of the active element (T).
