Page 26: Design Consideration Of Sleep To Wake Mode In Digital Led Driver
IoT XENSIVTM lighting platform Getting started guide Test results Design consideration of sleep to wake mode in digital LED driver When customers design their XDPL8221 LED driver, it is required to check the circuit to avoid failure recovery of the LED from dim off mode. According to the application note for the XDPL8221 UART, a sync. and a dimming command are required to wake XDPL8221 up from dim off, but hardware needs to support this operation too. -
Page 27: Possible Solution
IoT XENSIVTM lighting platform Getting started guide Test results In auto-restart mode, the acknowledge byte (0x00) to XMC1302 requires 300 to 1000 µs after XDPL8221 receives the sync. command. If XMC1302 doesn’t send the dimming level command to XDPL8221 within 148 ms, XDPL8221 resets and restarts automatically when V drops from the peak voltage. -
