... Driver Logic Input 2. Drive PWM2 with the signal that controls the MP8042 OUT2. Drive PWM high to turn on the high-side switch; drive PWM low to turn on the low-side switch. 6 FAULT Fault Output. A low output at FAULT indicates that the MP8042 has detected an over temperature, over current condition or the voltage to the driver is less than 5V. This output is open drain. ...
