Infineon Technologies TLE42064GXUMA1

Overview

TLE42064GXUMA1 from Infineon Technologies is an AEC-Q100 qualified H-bridge driver IC designed for automotive headlight beam control with DC brush motors. 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. Used in manual and automatic static beam adjustment systems.

For engineers reviewing the TLE42064GXUMA1 datasheet, TLE42064GXUMA1 pinout, TLE42064GXUMA1 application, or TLE42064GXUMA1 equivalent, key selection criteria include its 8–18 V operating supply range, 1.2 V typical total saturation voltage at 0.4 A, dual-output H-bridge topology with active braking, and PG-DSO-14-22 thermally enhanced package for automotive motor control.

Technical Context

The device implements a dual half-bridge architecture with integrated clamp diodes, internal window comparator on REF input, and dedicated RANGE pin for potentiometer stroke adaptation. Its servo amplifier supports external resistor programming of positive/negative hysteresis and deadband-enabling precise angular positioning of headlight actuators.

Fault management includes immediate motor stop and active braking (brake high) during short-to-GND, short-to-VS, or open-load conditions. Protection logic operates independently of MCU control, ensuring fail-safe behavior without software intervention under critical faults.

FAQ

What is the purpose of the RANGE pin on TLE42064GXUMA1?

The RANGE pin sets the lower switch-off threshold for the reference potentiometer input (REF), increasing it to 1.34 V (typ.) versus 0.9 V in the TLE42062G variant. This allows compatibility with potentiometers exhibiting larger voltage strokes, enabling broader use across multiple headlight actuator designs without hardware redesign.

Does TLE42064GXUMA1 require external flyback diodes?

No. The device integrates clamp diodes across both OUT1 and OUT2 outputs, eliminating the need for external flyback diodes. This reduces bill-of-materials count and PCB footprint-critical for space-constrained headlamp control modules where layout area is at a premium.

How does the TLE42064GXUMA1 respond to an open-load (broken wire) condition?

Upon detecting an open-load condition-identified by absence of expected current flow and feedback response-the device immediately halts motor operation and activates active braking (both OUT1 and OUT2 driven high), holding the motor in a safe, stationary state until reset or normal operation resumes.

Can TLE42064GXUMA1 operate from a 24 V truck battery system?

No. Its absolute maximum supply voltage is 45 V, but its overvoltage lockout triggers at 20.5–23 V, and functional operating range is limited to 8–18 V. For 24 V commercial vehicle applications, a pre-regulator stage or alternative 24 V-rated driver (e.g., BTS724G) must be used upstream.
