Typical values are for TJ = 25°C. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT TIMING tNRESET Reset pulse width 10 μs From shutdown into DC light mode 1.4 ms HC_SEL = 0, ILED = 100mA Start-up time From shutdown into voltage mode via ENVM 550 μs HC_SEL = 0, IOUT = 0mA MODE_CTRL[1:0] = 10, HC_SEL = 0 400 μs ILED2 = from 0mA to 800mA LED current settling time(1) triggered by a rising edge on FLASH_SYNC MODE_CTRL[1:0] = 10, HC_SEL = 1 16 μs ILED2 = from 0mA to 1800mA LED current settling time(1) triggered MODE_CTRL[1:0] = 10, HC_SEL = 0 15 μs by Tx-MASK ILED2 = from 800mA to 350mA (1) Settling time to ±15% of the target value.
