In case of an overtemperature condition, the temperature sensor will disable the transmitter (see Figure 1). After the device cools down, the transmitter is activated again (see Figure 7). A hysteresis is implemented within the temperature sensor. supply voltage VCC power-down reset level V CC(UV) normal-operating mode stand-by mode normal-operating mode 1) NEN = 0 NRM = 1 1) Assuming the logical signals on the pin NEN and on the pin NRM keep its values during the undervoltage event. In this case NEN remains “low“ and NRM remains “high“. delay time undervoltage recovery t Delay(UV) hysteresis VCC(UV,H) TxD t t CANH CANL RxD t Overtemperature event TJ t TJSD (shut-down temperature) Cool Down switch-on transmitter ΔT |
