Product details
Overview
TLE6286GDUMA1 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 TLE6286GDUMA1 datasheet, TLE6286GDUMA1 pinout, TLE6286GDUMA1 application, or TLE6286GDUMA1 equivalent, this device serves as a system-level LIN node controller with sleep-mode current optimization, watchdog supervision, and battery-supply robustness for automotive ECU designs requiring integrated power and communication.
Technical Context
The TLE6286GDUMA1 integrates two functionally independent die-LIN transceiver and LDO regulator-in a single P-DSO-16-11 package. Its transceiver includes internal 30 kΩ bus pull-up, dominant-state LOW logic, and bus short-to-GND detection during sleep mode via INHO-controlled termination.
The regulator features bandgap-referenced control amplifier, saturation current limiting, thermal shutdown, and reset generation triggered by VCCO droop below 1.35 V (via external RC on RD/RO pins). Sleep/wake sequencing is managed through ENLIN, INHI, and INHO signals with defined timing states per Figure 3.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| LIN Data Rate | Up to 20 kBaud - supports full-speed LIN 2.0 messaging without external clock conditioning |
| Regulator Output | 5 V ±2% at 200 mA - powers MCU and peripheral ICs directly; stable under load step and temperature variation |
| Sleep Current | < 100 µA - enables ultra-low-power ECU standby without external regulator disable circuitry |
| Bus Fault Protection | Short-to-battery and short-to-ground - maintains functionality during wiring faults in 12 V automotive systems |
| Operating Temp | −40 °C to +150 °C - qualified for under-hood and module-integrated automotive locations |
| Watchdog Input | Rising-edge triggered on WD pin - monitors MCU activity and forces reset if no edge occurs within timeout window |
| Reset Threshold | 1.35 V on RD pin - initiates RO open-collector reset pulse when VCCO drops below regulation limit |
Pinout & Package
P-DSO-16-11: 16-pin plastic dual small-outline package with exposed thermal pad, 1.27 mm pitch, RoHS-compliant, designed for surface-mount reflow assembly and enhanced thermal dissipation in automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | GND | Power and signal ground reference; connected to thermal pad for heat sinking |
| 2 | RD | Reset delay capacitor connection - sets reset pulse duration and release timing after VCCO recovery |
| 3 | WD | Watchdog input - rising edge resets internal watchdog timer; failure triggers RO reset |
| 4 | VCCO | 5 V regulated output - supplies external loads; requires 22 µF/ESR < 3 Ω ceramic capacitor |
| 5 | INHO | Inhibit LIN output - controls external voltage regulator enable/disable during sleep/wake transitions |
| 6 | RxD | Receive data output - open-drain, pulled HIGH internally; driven LOW during dominant bus state |
| 7 | ENLIN | Enable LIN input - TTL-compatible; HIGH enables transceiver, LOW forces sleep mode |
| 10 | VCCI | 5 V supply input - powers transceiver core; decoupled with 100 nF + 22 µF capacitors |
| 11 | TxD | Transmit data input - TTL-compatible; LOW initiates dominant bus state |
| 12 | BUS | LIN bus I/O - bidirectional single-wire interface with internal 30 kΩ pull-up to VBAT |
| 13 | VBAT | Battery supply input - accepts 5.5–27 V; requires reverse-current diode and 100 nF + 22 µF filtering |
| 14 | INHI | Inhibit voltage regulator input - TTL HIGH enables internal LDO; floating or tied to VBAT for always-on operation |
| 15 | RO | Reset output - open-collector; sinks current when VCCO drops below threshold or watchdog times out |
Key Features
| Feature | Design Value |
|---|---|
| Integrated LIN Transceiver + LDO | Single-chip solution eliminates discrete regulator and level-shifting components in LIN node design |
| Bus Short-to-Ground Detection | Automatically disables master termination path during sleep to prevent parasitic battery drain in parked vehicles |
| Controlled Sleep/Wake Sequencing | ENLIN, INHO, and INHI pins coordinate transceiver and regulator power states without MCU firmware intervention |
| Thermal Shutdown Protection | Halts regulator output above 150 °C and resumes after cooldown - prevents permanent damage in high-ambient environments |
| Reset Generation with Adjustable Delay | RD pin RC network sets precise reset hold time and release timing for reliable MCU boot synchronization |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LIN transceiver with integrated regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC33661 | Includes LIN 2.1 compliance and enhanced ESD rating (±8 kV HBM); lacks integrated watchdog and RO reset output | Requires external reset supervisor IC for MCU reset coordination; better suited for new designs targeting latest LIN spec | Select when LIN 2.1 conformance and higher ESD immunity are mandatory, and external reset logic is acceptable |
| TLIN1029 | Supports SAE J2602; offers programmable slew rate and wake-up filter; no integrated voltage regulator (requires external LDO) | Needs separate 5 V regulator and reset circuit; optimized for low-EMI bus signaling in safety-critical zones | Select when design prioritizes electromagnetic compatibility over integration density and cost-per-node |
Compared with MC33661 and TLIN1029, the TLE6286GDUMA1 provides tighter system integration via on-die regulator and watchdog, reducing component count and PCB area-ideal for cost-sensitive, space-constrained automotive nodes where LIN 1.3/2.0 compliance suffices.

FAQ
What is the maximum allowable VBAT input voltage for continuous operation?
The TLE6286GDUMA1 supports VBAT input from 5.5 V to 27 V under normal operating conditions. Absolute maximum rating is 32 V for transient spikes per ISO 7637-2 Pulse 1 and Pulse 2a, but sustained operation above 27 V risks thermal overload and premature shutdown due to internal power dissipation limits in the regulator section.
Can the internal voltage regulator be disabled while keeping the LIN transceiver active?
Yes. Tie INHI to GND to disable the internal LDO, then supply VCCI externally with a stable 5 V source. The transceiver remains fully functional with ENLIN HIGH, and INHO becomes inactive. This configuration is used when an external high-accuracy or higher-current regulator is preferred for system-level power architecture.
How does the BUS short-to-GND feature operate during sleep mode?
During sleep mode (ENLIN LOW), the TLE6286GDUMA1 disconnects the internal 30 kΩ bus pull-up from VBAT and routes it instead to INHO. If INHO is connected to an external regulator enable input, the pull-up path is broken entirely-eliminating the ~0.4 mA leakage current that would otherwise discharge the battery over weeks in parked vehicles.
Is the TLE6286GDUMA1 compliant with AEC-Q100 qualification?
Yes. The TLE6286GDUMA1 is qualified to AEC-Q100 Grade 1 (−40 °C to +125 °C ambient) and Grade 0 (−40 °C to +150 °C junction) per Infineon's official product documentation. Full qualification report includes HTOL, TC, ESD, and mechanical stress testing aligned with automotive reliability requirements.
