Digital pulse width modulator with built-in protection functions for over current, over voltage and temperature |
摘要 |
An apparatus for providing over current protection for a digital pulse width modulator is disclosed. The apparatus includes first logic circuitry for generating a primary interrupt indicating that a detected output current is greater than a threshold current. Second logic circuitry generates a secondary input responsive to the occurrence to the primary interrupt for a predetermined number of times.
