• Manufacturer Part Number: TLE 8458G
• Manufacturer: Infineon Technologies

Specifications of TLE 8458G

• Packages: PG-DSO-8
• Transmission Ratemax: 20.0 kbit/s
• Quiescent Current (max.): < 10 µA sleep mode
• Bus Wake-up Capability: Yes
• Additional Features: Vreg, EN, WK
• Wake-up Inputs: Bus wake-up + wake-up pin

5.2.3
The Stop Mode is a Low Power Mode, meaning the quiescent current of the TLE8458Gx is reduced to a minimum,
while the device is still able to recognized wake - up events. The following functions are available in Stop Mode:
•
•
•
•
•
•
•
•
Entering Stop Mode is only possible from the Normal Operation Mode, regardless if the device is in Normal Slope
Mode or Software Flash Mode. Setting the signal on the EN pin to LOW, followed by a LOW signal on the TxD pin
for the time
5.2.4
The Sleep Mode is a Low Power Mode as well, in comparison to the Stop Mode, the quiescent current of the
TLE8458Gx is even further reduced. In Sleep Mode the TLE8458Gx is able as well to recognized Wake - Up
events.
The Wake - Up behavior in Sleep Mode is the same as in Stop Mode. The only difference between Sleep Mode
and Stop Mode is, that in Stop Mode the output voltage
disabled.
Sleep Mode can be entered from Normal Operation Mode by setting the EN pin to LOW and simultaneously setting
the TxD pin to HIGH for the time
setting the signal on the TxD pin to HIGH for the time
Data Sheet
The power supply
The LIN transceiver output stage is disabled, no communication to the LIN bus is possible.
The LIN transceiver input receiver is disabled.
The internal LIN bus termination is switched off.
The TxD input and the RxD output is inactive.
The EN input is active. A HIGH signal on the EN pin changes the operation mode to Normal Operation Mode.
The LIN bus Wake - Up receiver is active, a Wake - Up event on the LIN bus changes the operation mode to
Stand-By Mode.
The wake input WK is active, a Wake - Up event on the WK pin changes the operation mode to Stand-By
Mode.
