ZHCSJY5D June 2019 – June 2022 TLIN1021-Q1
PRODUCTION DATA
The TLIN1021-Q1 has three functional modes of operation: normal, sleep, and standby. The next sections describe these modes and how the device transitions between the different modes. Figure 9-4 graphically shows the relationship while Table 9-1 shows the state of pins.
MODE | EN | TXD | RXD | INH | LIN BUS TERMINATION | TRANSMITTER | COMMENT |
---|---|---|---|---|---|---|---|
Sleep | Low | Weak pull-down | Floating | Floating | Weak current pull-up | Off | |
Standby | Low | weak pull-down if LIN bus wake-up; Strong pull-down if a local wake-up event (WAKE pin) | Low | High | 45 kΩ | Off | Wake-up event detected, waiting on MCU to set EN |
Normal | High | High: recessive state Low: dominant state | LIN Bus Data | High | 45 kΩ | On | LIN transmission up to 20 kbps |
