TLE 6285
In case the voltage regulator control input is not connected to INH output or the
microcontroller is active respectively, the TLE 6285 can be set in normal operation mode
without a wake-up via the communication bus.
LIN Transceiver
The LIN Transceiver has already a pull-up resistor of 30 k as termination implemented.
There is also a diode in this path, to protect the circuit from feedback of voltages from
the bus line to the power supply. To configure the TLE 6285 as a master node, an
additional external termination resistor of 1 k
is required. To avoid reverse currents
from the bus line into the battery supply line in case of an unpowered node, it is also
recommended to place a diode in series to the external pull-up. For small systems (low
bus capacitance) the EMC performance of the system is supported by an additional
capacitor of at least 1 nF in the master node (see
Figure
5,
Application
Example).
V
An capacitor of 10
F at the supply voltage input
buffers the input voltage. In
S
combination with the required reverse polarity diode this prevents the device from
detecting power down conditions in case of negative transients on the supply line.
Input Capacitor
C
The input capacitor
is necessary for compensation of line influences. Using a resistor
I
C
of approx. 1
in series with
, the oscillating circuit consisting of input inductivity and
I
input capacitance can be damped. The output capacitor is necessary for the stability of
the regulating circuit. Stability is guaranteed at values
22 F and an ESR of
5
within the operating temperature range. For small tolerances of the reset delay the
spread of the capacitance of the delay capacitor and its temperature coefficient should
be noted.
Voltage Regulator
The TLE 6285 incorporates a PNP based very low drop linear voltage regular. It
V
V
regulates the output voltage to
= 5 V for an input voltage range of 6 V
35V.
CC
I
The control circuit protects the device against potential caused by damages overcurrent
and overtemperature.
The internal control circuit achieves a 5 V output voltage with a tolerance of 2% in the
T
temperature range of
= -40 to 125 C.
j
The device includes a power on reset and an under voltage reset function with adjustable
reset delay time and adjustable reset switching threshold as well as a sense control/early
warning function. The device includes an inhibit function to disable it when the ECU is
not used for example while the motor is off.
V
The reset logic compares the output voltage
to an internal threshold. If the output
CC
C
voltage drops below this level, the external reset delay capacitor
is discharged. When

V
is lower than
, the reset output RO is switched Low. If the output voltage drop is
