PRODUCTION DATA
During a UVIO, UVCC or TSD fault the TCAN114x-Q1 automatically does the following to keep the digital core in a known state.
VSUP | VIO | VCC | DEVICE STATE | BUS | RXD |
---|---|---|---|---|---|
> UVSUP | > UVIO | > UVCC | Normal | Per TXD | Mirrors Bus |
> UVSUP | > UVIO | < UVCC | Fail-safe or Sleep | High Impedance | High (Recessive) |
< UVSUP | > UVIO | NA | Power Off | High Impedance | High (Recessive) |
> UVSUP | < UVIO | > UVCC | Fail-safe or UVIO Protected → Sleep | High Impedance | High Impedance |
> UVSUP | < UVIO | < UVCC | Fail-safe or Sleep | High Impedance | High Impedance |
< UVSUP | < UVIO | NA | Power Off | High Impedance | High Impedance |
