30 / 122 page  Figure 16. Active discharge function GADG0501181510PS The active discharge is performed by the PullDown sink for a duration configurable in ACTIVE_DSCHRG_TIM[3:0], see Table 20. The sink current is selected as shown in Table 19. In Table 19 is reported the Pull Up current values when binary lambda mode is active, and the Pull Down current value when Active discharge based on SEL, MODE and the control signal (see Figure 13): control signal is considered as it if MODE=0; it is considered at its negated value if MODE=1. Table 19. Lambda IO stage configuration in LSF mode LSF_MD_x=1 SEL[2:0]=111 CV[2:0] Current Value Pullup VDD5V Current Value Pullup Vvar Active Discharge Current Value Pull Down 111 500 µA 20 µA 500 µA 110 250 µA 20 µA 100 µA L9966 Binary Lambda mode DS12459 - Rev 10 page 30/122 |
