After VS is higher than the VS undervoltage threshold VSth, the IC mode changes from Unpowered Mode to Fail-safe Mode. The VCC output voltage reaches its nominal value after tVCC. This time, tVCC, depends on the VCC capacitor and the load. The NRES is low for the reset time delay treset. During this time, treset, no mode change is possible. IF VS drops below VSth, then the IC switches to Unpowered Mode. The behavior of VCC, NRES and LIN is shown in Figure 4-8. The watchdog needs to be triggered. Figure 4-8. VCC versus VS for the VCC = 3.3V Regulator 4.7 High-speed Mode If SP_MODE pin is high and the IC is in Normal Mode, the slew rate control is switched off. The slope time of the LIN falling edge is tS_Fall < 2µs. The slope time of the LIN rising edge strongly depends on the LIN capacitive and resistive load. To achieve a high baud rate it is recommended to use a small resistor (500 Ω) and a low capacitor. This allows very fast data transmission up to 200kBaud, e.g., for electronic control (ECU) tests and microcontroller program or data download. In this mode superior EMC performance is not guaranteed.
