PRODUCTION DATA.
The PWRGOOD signal is defined as an early warning signal that alerts the DLPC4422 device a specified amount of time before the DC supply voltages drop below specifications. This allows the DLPC4422 device to park the DMD and to place the system into reset, ensuring the integrity of future operation. For practical reasons, TI recommends that the monitor sensing PWRGOOD be on the input side of supply regulators.
