DLPS052 October 2015 DLPA3000
The DLPA3000 has the capability to flag for several faults in the system, such as overheating, low battery, power good, and overvoltage faults. If a certain fault condition occurs, one or more bits in the interrupt register (0x0C) will be set. The setting of a bit in register 0x0C will trigger an interrupt event, which will pulldown the INT_Z pin. Interrupts can be masked by setting the respective MASK bits in register 0x0D. Setting a MASK bit will prevent that the INT_Z is pulled low for the particular fault condition. Some high-level faults are composed of multiple low-level faults. The high-level faults can be read in register 0x0C, while the lower-level faults can be read in registers 0x027 through 0x2A. An overview of the faults and how they are related is given in Table 5.
