Product details
Overview
TLE62582GXUMA1 from Infineon Technologies is a LIN transceiver IC designed as a physical-layer interface between protocol controller and single-wire LIN bus in automotive systems. It supports LIN 1.2/1.3/2.0 and ISO 9141, operates at up to 20 kBaud, features integrated 30 kΩ bus pull-up, and delivers <10 µA standby current. It is used in body control modules for door lock, window lift, and seat position control.
For engineers reviewing the TLE62582GXUMA1 datasheet, TLE62582GXUMA1 pinout, TLE62582GXUMA1 application, or TLE62582GXUMA1 equivalent, key selection criteria include bus wake-up capability, AEC-Q100 qualification, thermal shutdown at 150–190 °C, 6–35 V battery supply range, and PG-DSO-8 package compatibility with automotive PCB layouts.
Technical Context
The TLE62582GXUMA1 implements a Smart Power Technology SPT® architecture integrating bipolar/CMOS control logic with DMOS power stages. Its receiver detects dominant/recessive states via internal comparator with hysteresis, while the driver stage provides controlled slew-rate output to meet LIN EMC requirements.
It supports three operational modes-normal, standby, and wake-up-controlled by the ENN (Enable Not) input. Bus wake-up detection triggers RxD low flag before automatic transition to normal mode, enabling low-power node architectures compliant with LIN specification timing constraints.
Key Specifications

Pinout & Package
Package: PG-DSO-8 (Plastic Dual Small Outline, 8-pin, exposed pad, RoHS-compliant).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 RxD | Receive data output | Open-drain output with internal pull-up; asserts LOW during dominant bus state or wake-up event |
| 2 ENN | Enable Not input | Active-low enable; HIGH forces standby mode; internal 30 kΩ pull-up simplifies microcontroller interface |
| 3 VCC | 5 V logic supply | Powers internal logic and level-shifting circuitry; requires local 100 nF decoupling |
| 4 TxD | Transmit data input | CMOS-compatible input with internal pull-up; LOW initiates dominant bus state |
| 5 GND | Ground reference | Common return path for logic and bus driver; must be low-inductance connection to minimize EMI |
| 6 Bus | Single-wire bus I/O | Bi-directional line with integrated 30 kΩ pull-up; connects directly to LIN bus without external termination |
| 7 VS | Battery supply input | High-side power rail for driver stage; withstands 40 V transient per ISO 7637-2 Pulse 5a |
| 8 n.c. | No connect | Unbonded pin; must remain unconnected and unpopulated on PCB |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LIN transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLIN1029DRBR | Higher ESD rating (±8 kV HBM), integrated voltage regulator (3.3 V), no VS pin | Designed for 3.3 V MCU systems; lacks direct battery-supplied high-side driver stage | Select when system uses regulated 3.3 V supply and requires enhanced ESD robustness |
| MC33661DTBR2G | Supports LIN 2.2A, includes integrated watchdog timer and VREG, higher quiescent current (25 µA) | Targets safety-critical nodes requiring diagnostic supervision; not AEC-Q100 Grade 1 qualified | Select when functional safety diagnostics (e.g., watchdog timeout) are required alongside LIN communication |
Compared with TLIN1029DRBR and MC33661DTBR2G, the TLE62582GXUMA1 offers direct VS-battery interface, lowest standby current (<10 µA), and proven AEC-Q100 Grade 1 qualification - making it optimal for cost-sensitive, thermally demanding, and battery-life-critical body electronics.

FAQ
What is the function of the ENN pin on the TLE62582GXUMA1?
The ENN (Enable Not) pin is an active-low input that controls operational mode: pulled LOW to enable normal operation, and driven HIGH to enter standby mode. It features an internal 30 kΩ pull-up resistor, allowing direct connection to a microcontroller GPIO without external biasing. In standby, the device draws <10 µA while retaining bus wake-up capability via RxD assertion.
Does the TLE62582GXUMA1 require an external termination resistor?
Yes - although the TLE62582GXUMA1 integrates a 30 kΩ bus pull-up, an external 1 kΩ termination resistor is required at the master node to meet LIN specification timing for dominant-to-recessive transitions. This resistor ensures proper signal edge rates and bus voltage levels, especially in systems with higher bus capacitance or longer cable runs.
How does the TLE62582GXUMA1 handle bus short-circuit conditions?
The TLE62582GXUMA1 driver stage includes inherent short-circuit protection to both ground and battery (VS). During a short, output current is self-limited, and thermal shutdown activates if junction temperature exceeds 150–190 °C. After fault removal and cooldown, the device automatically recovers without requiring reset - critical for unattended automotive nodes.
Is the TLE62582GXUMA1 compatible with LIN 2.2A or later revisions?
No - the TLE62582GXUMA1 is specified for LIN 1.2, 1.3, and 2.0 only. It does not support LIN 2.2A features such as enhanced checksum, configurable frame IDs, or improved error detection. For LIN 2.2A compliance, consider Infineon's newer TLIN series or NXP's TJA1021 family, which explicitly list 2.2A support in their datasheets.
