Figure 17. Input voltage range in LPOFF, LPON, and NORMAL mode

• VSUP > 28 V: potential thermal limitation (risk of TSD detection)

• VSUP > 18 V: extended high-voltage transient operation (Load dump)

• VSUP < 5.5 V: linear regulator needs a minimum of 5.5 V input when configured to deliver 5 V output. AMUX,

CAN and IO specified for VSUP > 5.5 V

• VSUP < VBOS_UV in LPOFF mode: wake-up capability of the device is not guaranteed anymore, risk of POR

• VSUP < V1UV_LP in LPON mode: undervoltage detected on V1 in LPON mode leads the device to Fail-safe

mode, with all regulators OFF

• VSUP < VBOS_UV in NORMAL mode: the device goes to Fail-safe mode, with all regulators OFF
