Infineon Technologies TLE42064GXUMA2

Overview

TLE42064GXUMA2 from Infineon Technologies is an automotive-grade H-bridge driver IC designed for DC-brush motor control in headlight beam adjustment systems. It delivers up to 0.8 A continuous output current, features programmable servo-loop parameters (hysteresis, deadband, angle amplification), and integrates over/under-voltage lockout, short-circuit protection, and thermal shutdown with hysteresis. Its operation is validated for 8–18 V supply range and −40 °C to +150 °C junction temperature.

For engineers reviewing the TLE42064GXUMA2 datasheet, TLE42064GXUMA2 pinout, TLE42064GXUMA2 application, or TLE42064GXUMA2 equivalent, key selection criteria include its dual-output saturation voltage (1.2 V total @ 0.4 A), Range pin programmability for potentiometer stroke adaptation, active braking capability during fault conditions, and PG-DSO-14-22 package compatibility with automotive PCB layout constraints.

Technical Context

The TLE42064GXUMA2 implements a dual half-bridge architecture with integrated protection logic, using bipolar high-voltage DOPL technology. Its servo amplifier accepts feedback (FB) and reference (REF) inputs, while the RANGE pin configures the operational window of the internal window comparator-specifically tuned for wider potentiometer stroke coverage versus the TLE4206-2G variant.

Protection functions operate independently: UVLO activates at 7.4 V (ON) / 6.9 V (OFF), OVLO at 20.5 V (OFF) / 17.5 V (ON), and thermal shutdown engages with hysteresis above 150 °C. Output clamping diodes support bidirectional energy recovery, and NC pin (Pin 7) is electrically isolated from internal circuitry.

Key Specifications

Pinout & Package

Delivered in the thermally enhanced PG-DSO-14-22 package (green, RoHS-compliant), the TLE42064GXUMA2 uses a 14-pin exposed-pad SOIC footprint optimized for automotive motor drive applications. The exposed pad (Pins 3, 4, 5, 10, 11, 12) serves as primary thermal and ground path.

FAQ

What is the function of the RANGE pin on the TLE42064GXUMA2?

The RANGE pin configures the lower switch-off threshold of the internal window comparator to 1.34 V (typical), enabling support for reference potentiometers with extended mechanical stroke. It also provides short-circuit protection at the potentiometer itself. Unlike the TLE4206-2G, this higher threshold accommodates a broader range of commercially available potentiometers used in headlight leveling mechanisms.

Does the TLE42064GXUMA2 require external flyback diodes?

No. The device integrates clamp diodes on both OUT1 and OUT2 outputs with forward voltages of ≤1.5 V (upper) and ≤1.4 V (lower) at 0.4 A. These diodes safely dissipate motor back-EMF energy during switching transitions, eliminating the need for external flyback components and reducing PCB area and BOM cost.

How does the TLE42064GXUMA2 respond to a broken wire fault?

Upon detecting an open-circuit condition (broken wire) at the motor terminals, the device immediately halts motor motion and applies active braking by driving both OUT1 and OUT2 high ("brake high"). This ensures rapid, controlled deceleration and prevents uncommanded beam drift - a critical fail-safe behavior mandated for automotive lighting systems.

Can the TLE42064GXUMA2 operate from a 24 V truck battery system?

No. Its absolute maximum supply voltage is 45 V, but its functional operating range is strictly 8–18 V per specification. Operation above 18 V triggers overvoltage lockout (OVLO), disabling outputs until VS drops below 17.5 V. For 24 V commercial vehicle applications, a pre-regulator stage or alternative 24 V-rated driver (e.g., BTS724G) is required.
