Infineon Technologies TLE4209GXUMA1

Overview

TLE4209GXUMA1 from Infineon Technologies is a protected H-bridge DC motor driver IC optimized for automotive manual headlight beam control and industrial servo applications. It delivers up to 0.7 A continuous output current, features programmable hysteresis and deadband via external resistors, includes integrated short-circuit, overtemperature, and over/under-voltage lockout protection, and uses the PG-DSO-14 surface-mount power package.

For engineers reviewing the TLE4209GXUMA1 datasheet, TLE4209GXUMA1 pinout, TLE4209GXUMA1 application, or TLE4209GXUMA1 equivalent, key selection criteria include its 0.7 A continuous drive capability, dual-output saturation voltage (≤2.5 V total at 0.7 A), programmable servo-loop parameters, AEC-Q100 qualification, and PG-DSO-14 thermal performance with R_thJA = 65 K/W under enhanced copper layout.

Technical Context

The TLE4209GXUMA1 implements a bipolar high-voltage DOPL process-based H-bridge with two independently controlled half-bridges (OUT1/OUT2), internal clamp diodes, and a window comparator for input line monitoring. Its servo control architecture accepts analog feedback (FB), reference (REF), range (RANGE), and hysteresis (HYST) inputs to configure position loop behavior.

Protection logic responds to short-to-GND, short-to-VS, and open-load faults by forcing immediate brake condition. Overvoltage lockout triggers at 20.5 V (typ.), undervoltage at 7.4 V (typ.), and thermal shutdown activates with hysteresis above 150 °C junction temperature.

FAQ

What is the maximum continuous motor current supported by TLE4209GXUMA1?

The TLE4209GXUMA1 supports up to 0.7 A continuous current per output channel (OUT1 or OUT2) under specified thermal conditions: ambient ≤+105 °C with 600 mm² copper cooling area connected to six GND pins. Peak currents beyond this require derating based on R_thJA = 65 K/W and junction temperature limits of 150 °C.

How does the hysteresis (HYST) pin function in closed-loop control?

The HYST pin accepts an external current to set the hysteresis window width for the internal window comparator. With typical gain of 0.95×, a 20 μA input produces ~19 μA output current that defines the ±4% threshold spread (VHYW/VS). This directly configures mechanical backlash compensation in headlight leveling systems without software calibration.

Can TLE4209GXUMA1 drive inductive loads other than DC motors?

Yes - it can drive any inductive load within its 0.7 A/18 V rating and thermal limits, including solenoids and relays. Internal clamp diodes protect against flyback voltage, and short-circuit protection engages on sustained overcurrent. However, its servo-loop interface (FB/REF/RANGE/HYST) is optimized for position feedback systems, not generic switching.

Is the NC pin (Pin 7) required to be left floating or grounded?

Pin 7 (NC) is internally unconnected and must remain electrically floating. Infineon's layout guidelines recommend either leaving it unconnected or tying it to GND via a 0 Ω resistor for mechanical stability - but never routing signal traces or applying voltage. Doing so avoids unintended coupling into adjacent high-current GND paths.
