ZHCSLW4A March 2020 – September 2020 TCAN1046-Q1
PRODUCTION DATA
The supply pin, VCC, has undervoltage detection that places the TCAN1046 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 Weak pull-down to ground(1) | High impedance |
Once the undervoltage condition is cleared and tMODE has expired the TCAN1046 transitions to normal mode and the host controller can send and receive CAN traffic again.
