SLLSF27D November 2018 – June 2022 TLIN1441-Q1
PRODUCTION DATA
nRST: Float
nRST: Float
The TLIN1441-Q1 has three functional modes of operation: normal, sleep, and standby. The next sections describes these modes as well as how the device moves between the different modes. Figure 9-7 graphically shows the relationship while Table 9-1 shows the state of pins.
Mode | RXD | LIN BUS Termination | Transmitter | Watchdog | SPI Pins | nINT Pin | nRST/ nWDR Pin | WAKE Pin | LIMP | Comment |
---|---|---|---|---|---|---|---|---|---|---|
Sleep | Floating | Weak current pull-up | Off | Off | Off | On | Floating | On | Off | nRST is internally connected to the LDO output which in sleep mode is off |
Standby | Low | 45 kΩ (typical) | Off | Off | On | On | On | On | Previous state prior to entering STBY | wake-up event detected, waiting on processors to set EN |
Normal | LIN Bus Data | 45 kΩ (typical) | On | On | On | On | On | On | Off but can be active | LIN transmission up to 20 kbps |
TSD Off | NA | Floating | 45 kΩ (typical) | Off | On | On | Floating | On | Off | nRST is floating but if OVCC is reached this value may show up on nRST pin |
Failsafe | Floating | Weak current pull-up | Off | Off | Off | On | Floating | On | On | Failsafe mode is sleep mode with LIMP on |
Mode | EN | RXD | LIN BUS Termination | Transmitter | Watchdog | nRST Pin | WAKE Pin | LIMP | Comment |
---|---|---|---|---|---|---|---|---|---|
Sleep | Low | Floating | Weak current pull-up | Off | Off | Floating | On | Off | nRST is internally connected to the LDO output which in sleep mode is off |
Standby | Low | Low | 45 kΩ (typical) | Off | Off | On | On | Previous state prior to entering STBY | Wake-up event detected, waiting on processors to set EN |
Normal | High | LIN Bus Data | 45 kΩ (typical) | On | On | On | On | Off but can be active | LIN transmission up to 20 kbps |
TSD Off | NA | Floating | 45 kΩ (typical) | Off | Off | Floating | On | Off | nRST is floating but if OVCC is reached this value may show up on nRST pin |
