9.4 Device Functional Modes
The TLIN1024A-Q1 has three functional modes of operation, normal, sleep, and standby. The next sections describe these modes as well as how the device moves between the different modes. Figure 9-4 graphically shows the relationship while Table 9-1 shows the state of pins.
Table 9-1 Operating Modes
| MODE | ENx | RXDx | LIN BUS TERMINATION | TRANSMITTER | COMMENT |
|---|---|---|---|---|---|
| Sleep | Low | Floating | Weak Current Pull-up | Off | |
| Standby | Low | Low | 45 kΩ (typical) | Off | Wake-up event detected, waiting on MCU to set EN |
| Normal | High | LINx Bus Data | 45 kΩ (typical) | On | LINx transmission up to 20 kbps |
