8.3.1.4.1 Discontinuous Mode Pulse Width Limit

The TPS99000-Q1 has a feature which limits the time duration of each discontinuous mode pulse. A count monitors the length of time current is applied to the LED during a pulse event and compares time to a programmable time limit. If the time limit expires before the light output threshold is reached, the discontinuous pulse is terminated. The pulses in both cases (photo level or time limit expiration) are terminated by enabling the S_EN1 low resistance shunt. This limits maximum brightness in the event photo feedback threshold is not reached. Independent RGB values for the discontinuous pulse width limit are supported. This process is illustrated in Figure 23.
