TLE9222
Overview
addition to transmit and receive functions, the TLE9222 provides low power standby operation, supply
voltage monitoring (undervoltage detection) as well as bus failure detection and represents an ESD-
protection barrier between the bus and the ECU.
The TLE9222 supports the following FlexRay functional classes:
• Functional class “Bus driver - bus guardian interface”
• Functional class “Bus driver logic level adaptation”
• Functional class “Bus driver remote wakeup”
• Functional class “Bus driver increased voltage amplitude transmitter”
In BD_Standby mode the quiescent current is decreased to a minimal level while still being able to detect
wake-up requests on the bus.
Fail Safe features, like failure detection and the power supply monitoring, combined with an easy accessible
status register support requirements for safety related applications with extended diagnostic features.
The TLE9222 is internally protected against transients on the bus pins, BP and BM. This makes it possible to
use the TLE9222 for implementing ECUs without additional external bus protection circuitry while fulfilling
ESD and ISO pulse requirements of car manufacturers. With its excellent EMC performance the TLE9222
provides a very high immunity against RF disturbances over a broad frequency range and transmits only a
minimal level of electromagnetic emission onto the bus.
The TLE9222 is integrated in a RoHS compliant PG-TSSOP-14 package. Using the latest Infineon Smart Power
Technology it is especially tailored to withstand the harsh conditions of the automotive environment and
qualification according to the AEC-Q100 standard.

4.2 Communication Controller Interface
The communication controller interface is the link between the TLE9222 and the FlexRay communication
controller, comprising three digital signals:
• TxEN (Transmit Data Enable Not) input
• TxD (Transmit Data) input
• RxD (Receive Data) output
The logical I/O levels of all three digital pins are adapted to the VIO digital reference voltage supply.

The communication controller interface drives the serial digital data stream available on the TxD input to the
FlexRay bus via the transmitter. Simultaneously the receiver of the TLE9222 monitors the data on the FlexRay
bus and transfers the data to a serial digital data stream back to the RxD output. A logical “low” signal on the
