If V1OV_TH2 ≤ V1 < 6.5 V → It causes a non recoverable failure and the device is forced to VBAT standby

mode (V1 is switched OFF and FORCED_SLEEP_V1OV (SR2) is raised after tOV1FILTER2). The internal

pull-down transistor which will discharge the decoupling capacitor through the RDISCHARGE is activated

If the VBAT stdby is caused by an output overvoltage on V1, the status flag stays set (V1_OV = 1).

At VSREG > VPOR (that is, VSREG power-on reset threshold), the LIN transceiver is enabled.

The LIN transmitter is disabled in case of the following errors:

•

Dominant TxD_L time out

•

LIN permanent recessive

•

Thermal shutdown 1

–

with thermal sensor “global” in mode “no cluster”
