Power stage control circuit |
摘要 |
The present invention discloses a power stage control circuit including: a driver circuit for controlling a power stage according to an error amplified signal; an error amplifier circuit for comparing a feedback voltage at a feedback terminal with a reference signal to generate the error amplified signal; a current generator circuit coupled to the feedback terminal for generating a fault detection current flowing to the feedback terminal; and a feedback terminal short detection circuit for generating a fault signal to stop the operation of the power stage when the feedback voltage is smaller than a short-circuit threshold voltage or when the fault detection current is larger than a short-circuit threshold current.
