Abstract
An integrated pulse-width modulation circuit with conditional temperature protection circuitry includes logic circuitry, a power output device, thermal shutdown circuitry to disable the power output device when the die temperature exceeds a predetermined limit, and a masking circuit that disables the thermal shutdown circuit during short term thermal increases such as those that occur when an inductive load turn off event takes place.
