Low electromagnetic emission driver

摘要

The invention concerns circuitry for controlling a power transistor (302) of a drive circuit arranged to drive an electrical component (301), the circuitry comprising: a variable current source (320) adapted to set the level of a current (I_DRIVE) for charging a control terminal of said power transistor; and a control circuit (326) adapted to control said variable current source in a continuous manner based on a feedback voltage (V OUT , A GATE ).
