Digital safety monitors
7.2.3.1
Illumination time monitor
The illumination time monitor is continuously sampling the PWM ON time applied via both
inputs and comparing the result with the value programmed in “TD_ILLUM_MAX register
(Address 0x1A36)”. In PWM mode the ON time (HIGH Time) is constrained to be maximum
15ms. Therefore, the value in the TD_ILLUM_MAX register shall be less the 15ms in this
mode. (Refer to Table 5: External PWM mode constraints).
If the actual PWM ON time is longer than the value programmed the current sinks get turned
off and the respective interrupt flag is set.
Figure 31 shows the actual implementation – in the 3rd frame (STROBE = yellow) the PWM ON
time changes from 4ms to 10ms – TD_ILLUM_MAX is programmed to 4.1ms.
The current sink (blue) is turned off immediately and the interrupt IRQ_N (green) is pulled to
GND. The interrupt “Illumination Duration” has been set and is informing the Host.
