SLLSFL9A July 2021 – December 2021 TCAN1046A-Q1
PRODUCTION DATA
The supply pin, VCC, has undervoltage detection that places the device into a protected state. This protects the bus during an undervoltage event on either supply pin.
VCC | DEVICE STATE | BUS | RXD PIN |
---|---|---|---|
> UVVCC | Normal | Per TXD | Mirrors bus |
< UVVCC | Protected | High impedance (1) | High impedance |
Once the undervoltage condition is cleared and tMODE has expired the TCAN1046A-Q1 transitions to normal mode and the host controller can send and receive CAN traffic again.
