TLE 7269G Infineon Technologies, TLE 7269G Datasheet - Page 16

• Manufacturer Part Number: TLE 7269G
• Manufacturer: Infineon Technologies

Specifications of TLE 7269G

• Packages: PG-DSO-14
• Transmission Ratemax: 20.0 kbit/s
• Quiescent Current (max.): < 10 µA sleep mode
• Bus Wake-up Capability: Yes
• Additional Features: 2 x LIN trx, INH, EN, WK, Vio
• Wake-up Inputs: Bus wake-up + wake-up pin

A transition from logical “High” to logical “Low” on the EN pin changes the operation mode from Normal Operation
mode to Sleep mode. If the TLE7269G is already in Sleep mode, changing the EN from “Low” to “High” results into
a mode change from Sleep mode to Normal Operation mode. If the device is in Stand-By mode a change from
“Low” to “High” on the EN pin changes the mode to Normal Operation mode (see

of the whole LIN network. To avoid any blocking of the LIN network by a local ECU the TLE7269G has an
integrated Power-On reset at the supply

the operation mode to Stand-By mode. In Stand-By mode the output stage of the TLE7269G is disabled and no
communication to the LIN bus is possible. The internal bus termination remains active as well as the INH pins (see
