Infineon Technologies TLE6286G

Overview

TLE6286G from Infineon Technologies is a LIN transceiver with integrated 5 V low-dropout voltage regulator, designed as a physical-layer interface between microcontroller and single-wire LIN bus in automotive body electronics. It supports up to 20 kBaud transmission, complies with LIN 1.3/2.0 and ISO 9141 standards, features bus short-to-ground protection, and delivers 200 mA regulated output with ±2% tolerance.

For engineers reviewing the TLE6286G datasheet, TLE6286G pinout, TLE6286G application, or TLE6286G equivalent, this device is selected for LIN node power management, sleep-mode wake-up coordination, bus fault resilience, and integrated regulator control-critical for door modules, seat controllers, and lighting ECUs requiring AEC-Q100-compliant communication interfaces.

Technical Context

The TLE6286G integrates two functionally independent chips in one P-DSO-16-11 package: a LIN transceiver with 30 kΩ internal bus pull-up and dominant-state LOW signaling, and a standalone LDO regulator with adjustable enable via INHO/INHI logic. Its watchdog input (WD) accepts rising-edge triggers for MCU supervision, while RxD provides open-collector wake-up flagging during bus-initiated exit from sleep mode.

Sleep mode is entered by pulling ENLIN low, disabling transceiver operation and asserting INHO low to shut down external regulators; wake-up occurs automatically on valid LIN frame detection, setting INHO high and RxD low until normal mode resumes. Thermal shutdown and overtemperature protection are implemented at chip level with no external components required.

FAQ

What is the maximum allowable load capacitance on the VCCO pin?

The VCCO pin requires a 22 µF low-ESR capacitor with ESR < 3 Ω at 10 kHz for stable regulation. Exceeding this capacitance or using high-ESR types may cause oscillation or dropout under transient load conditions. No maximum capacitance limit is specified, but stability must be verified per layout and load profile.

How does the BUS short-to-GND feature operate during sleep mode?

During sleep mode, the TLE6286G internally disconnects the 30 kΩ bus pull-up from VBAT and routes it through INHO. When INHO is driven LOW (default in sleep), the pull-up is disabled, eliminating the 30–40 µA leakage path that would otherwise drain the battery via the master termination resistor.

Can the internal voltage regulator be bypassed for external regulation?

Yes. The internal LDO can be disabled by holding INHI LOW or floating it, allowing an external 5 V regulator to supply VCCI. In this configuration, VCCO is unused, and all transceiver functions remain fully operational with externally sourced VCCI.

Is the TLE6286G compliant with AEC-Q100?

Yes. The TLE6286G is qualified per AEC-Q100 Grade 1 (−40 °C to +125 °C ambient) and Grade 0 (−40 °C to +150 °C junction), with full automotive qualification including HTOL, TC, and ESD testing as documented in Infineon's release documentation.
