7.3.13.3 Under/Over Voltage Lockout

The supply terminals implement undervoltage and over voltage detection circuitry. If an undervoltage is detected, the TCAN1162x-Q1 transitions into either reset or sleep mode depending on the undervoltage fault. An undervoltage fault on VIO causes the SBC to transition into sleep mode while an undervoltage fault on the integrated regulator causes the SBC to transition to reset mode. The SBC remains in reset mode until the fault condition on the regulator is cleared.

If the over voltage fault is detected, the TCAN1162x-Q1 transitions into fail-safe mode. These mode changes place the device in a known state which protect the system from unintended behavior. See Table 7-1
