Modes of Reduced Current Consumption
4.2.1
Silent Mode
A falling edge at EN while TXD is high switches the IC into Silent mode. The TXD Signal has to
be logic high during the Mode Select window (see Figure 4-2 on page 6). For EN and TXD either
two independent outputs can be used, or two outputs from the same microcontroller port; in the
second case, the mode change is only one command.
In Silent mode the transmission path is disabled. Supply current from V
Batt is typically
I
VSsi = 40 A with no load at the VCC regulator.
The overall supply current from V
Batt is the result of 40 A plus the VCC regulator output current
I
VCCs.
The 5V regulator is in low tolerance mode (4.65V to 5.35V) and can source up to 50 mA. In
Silent mode the internal slave termination between pin LIN and pin VS is disabled to minimize
the power dissipation in case pin LIN is short-circuited to GND. Only a weak pull-up current (typ-
ically 10 A) between pin LIN and pin VS is present.
The Silent mode voltage is sufficient to run an external microcontroller on the ECU, for example
in Power Down mode. The undervoltage reset is V
CCthS < 4.4V. If an undervoltage condition
occurs, NRES is switched to low and the ATA6620N changes state to Pre-normal mode.
A falling edge at pin LIN followed by a dominant bus level maintained for a certain time period
(t
bus) results in a remote wake-up request. The device switches from Silent mode to Pre-normal
mode, then the internal LIN slave termination resistor is switched on. The remote wake-up
request is indicated by a low level at pin RXD to interrupt the microcontroller and a high level at
pin TXD (see Figure 4-3 on page 7).
With EN high, ATA6620N switches directly from Silent- via Pre-normal to Normal mode.
