... AU5783 and the J1850 network. The AU5783 contain a power on reset (POR) circuit, which is active at low voltages. This circuit insures that if the control input NSTB floating during power up, the device will be forced into the standby mode by the time the battery voltage rises to 4 ...

... Figure 3. This ratio metric behavior of the input threshold partially compensates for the reduced dominant level transmitted during low battery operation. The AU5783 features special robustness at its BAT and BUS pins hence the device is well protected for applications in the automotive environment. Specifically the BAT input is protected against 40 V load dump and jump start condition ...

... Note 4, Note 6 NOTES: 1. After power-on, the AU5783 enters standby mode since the input pins NSTB and 4X/LOOP are assumed to be floating. In standby mode the voltage regulator is enabled via the INH output, and therefore power is supplied to the microcontroller. When the microcontroller begins operation it will normally set the control inputs NSTB high and 4X/LOOP to low state in order to start normal operation of the AU5783 ...
