PRODUCTION DATA
The multiple fault could be reported out by the different voltage level through fault pins. The fault pin will be pulled down firstly for t(discharge) time in order to generate a falling edge trigger signal for the ADC of MCU. The t(discharge) time is also used as discharge process for LED open-circuit detection and output short-to-battery detection. After the discharge process, the fault pin will be pulled up to a specific voltage level according to the detected fault to achieve multiple fault report for safety critical system, as shown in Figure 7-5
