7.3.6 Undervoltage Lockout

The supply pins, VCC and VIO, have undervoltage detection that places the device into a protected state. This protects the bus during an undervoltage event on either supply pin.

Table 7-1 Undervoltage Lockout - TCAN3414
VCCDEVICE STATEBUSRXD PIN
> UVVCCNormal if STB = GND and SHDN = GNDPer TXDMirrors bus
> UVVCC Standby mode if STB = High and SHDN = GND Weak biased to GND VCC, Remote wake request
See Remote Wake Request via Wake-Up Pattern (WUP) in Standby Mode
> UVVCC Shutdown mode if SHDN = High Weak biased to GND VCC
< UVVCCProtectedHigh impedance High impedance

Once the undervoltage condition is cleared and tMODE or tSHDN2 has expired, the TCAN341x transitions to normal mode. The host controller again sends and receives CAN traffic.
