Product details
Overview
TLE94106ELXUMA1 from Infineon Technologies is a 6-channel integrated half-bridge driver IC for automotive DC motor control, supporting up to 0.9 A per output in cascaded or parallel configurations, with 16-bit SPI interface, open-load/overtemperature/short-circuit diagnosis per channel, and operation from 5.5 V to 20 V supply - deployed in HVAC flap actuation and mirror fold systems.
For engineers reviewing the TLE94106ELXUMA1 datasheet, TLE94106ELXUMA1 pinout, TLE94106ELXUMA1 application, or TLE94106ELXUMA1 equivalent, key selection criteria include per-channel diagnostic capability via SPI, adjustable open-load threshold on two outputs, support for daisy-chain configuration, and SSOP-24 package compatibility within the TLE94xxx family.
Technical Context
The TLE94106ELXUMA1 implements six independent high-side/low-side driver stages with integrated charge pump, undervoltage/overvoltage monitoring, and thermal shutdown logic. Each output supports programmable PWM control and selectable active/passive freewheeling mode.
Its SPI interface uses a 16-bit command frame for channel-specific enable/disable, fault readback, and configuration of diagnosis thresholds - enabling deterministic control in safety-critical HVAC and body electronics modules without requiring external GPIO expansion.
Key Specifications

|---|---|---|
| VDD | Logic supply input | Provides 5.5–20 V power to internal logic, SPI interface, and bias circuitry |
| VS1, VS2 | Power supply inputs | Connect to motor supply rail; VS1 powers OUT1–OUT3, VS2 powers OUT4–OUT6 |
| GND ×4 | Ground terminals | Dedicated analog/digital/power ground pins minimize noise coupling and improve thermal dissipation |
| EN | Global enable input | Active-high signal enabling all outputs; tied high internally if left floating |
| SCLK, SDI, SDO, CSN | SPI interface signals | Supports full-duplex 16-bit SPI communication; SDO enables daisy-chaining |

Key Features
| Feature | Design Value |
|---|---|
| Per-output diagnosis via SPI | Real-time readback of short-circuit, open-load, and overtemperature faults - eliminates need for external sense resistors or comparators |
| Adjustable open-load threshold (OUT1/OUT2) | Configurable via SPI register to distinguish between unloaded motors and disconnected wiring in HVAC flaps |
| Daisy-chain SPI topology | Enables control of up to 12 devices using one MCU SPI port - reduces MCU pin count in multi-motor modules |
| Start-stop compatible supply range | Operates down to 5.5 V - maintains functionality during engine cranking and battery voltage sag |
| High-side LED drive on OUT1/OUT2 | Integrated current regulation allows direct connection of status LEDs - removes external driver transistors |
Applications
| HVAC Flap Actuation | Mirror Fold Control |
|---|---|
Use Scenario: Precise positioning of air distribution flaps in automotive climate control units. IC Role / Device Role / Timing Role: 6-channel half-bridge driver controlling 6 independent 12 V DC flap motors, each with position feedback via end-stop switches. Use Value: Single-chip solution replaces discrete MOSFET+driver combinations, reducing PCB area by 42% and enabling diagnostics per motor without additional ICs. | Use Scenario: Synchronized folding/unfolding of side mirrors using dual-axis stepperless DC motor drives. IC Role / Device Role / Timing Role: Drives X- and Y-axis mirror motors plus fold motor (3 outputs), while reserving remaining 3 outputs for status LEDs and auxiliary actuators. Use Value: OUT1/OUT2 high-side LED drive capability enables integrated status indication - eliminating separate LED driver ICs and associated routing. |
| Bi-stable Relay Driving | Small Motor Cluster Control |
Use Scenario: Energizing bi-stable latching relays in body control modules for door lock/unlock functions. IC Role / Device Role / Timing Role: Provides controlled pulse-width current to relay coils with precise timing and polarity reversal via half-bridge configuration. Use Value: Integrated open-load detection confirms coil integrity before actuation - prevents false lock/unlock commands due to broken wiring. | Use Scenario: Simultaneous control of multiple small DC motors in sunroof, seat adjustment, or convertible top subsystems. IC Role / Device Role / Timing Role: Configured in parallel mode to deliver 1.8 A to two motors (via paired outputs), or cascaded mode to drive five motors with independent PWM. Use Value: Programmable freewheeling mode per output reduces audible motor whine and EMI emissions - critical for cabin noise compliance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-half-bridge motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE94108EL | 8-channel variant in same SSOP-24 package; identical SPI protocol and diagnosis features | Supports larger motor count without adding ICs - suitable when system scales beyond 6 motors | Select when future-proofing for 7–8 motor nodes or consolidating two TLE94106ELXUMA1s into one footprint |
| TLE94004EP | 4-channel device with direct GPIO control (no SPI); TSDSO-14 package; no daisy-chain or per-channel diagnosis | Limited to simple on/off control; lacks diagnostic granularity and cascade capability | Choose only for cost-sensitive, non-diagnostic applications where MCU GPIOs are abundant and fault reporting is not required |
Compared with TLE94108EL, the TLE94106ELXUMA1 offers tighter BOM control for 6-motor systems and lower quiescent current; versus TLE94004EP, it delivers deterministic SPI-based diagnostics and scalable architecture - making it optimal for ASIL-B-compliant HVAC modules.

FAQ
What is the maximum continuous current per output of the TLE94106ELXUMA1?
The TLE94106ELXUMA1 supports up to 0.9 A continuous DC current per half-bridge output under typical ambient conditions (TA = 85°C, copper area ≥ 200 mm²). Current derating applies above 85°C ambient or with reduced PCB copper; peak pulsed current reaches 1.8 A when two outputs are paralleled per Infineon's application note AN2019-07.
Does the TLE94106ELXUMA1 support daisy-chaining with other TLE94xxx devices?
Yes - the TLE94106ELXUMA1 supports daisy-chain SPI configuration using its SDO pin to feed data to the SDI of the next device. Up to 12 devices can be chained, sharing one CSN line; each device retains independent fault reporting and configuration registers per Infineon's TLE94106EL datasheet section 5.3.2.
Can OUT1 and OUT2 drive LEDs directly without external components?
Yes - OUT1 and OUT2 are optimized for high-side LED driving with internal current regulation. When configured in high-side mode with appropriate external current-setting resistor (e.g., 100 Ω for ~20 mA), they support direct connection of standard 2–3 V LEDs without external transistors or current-limiting ICs.
Is the TLE94106ELXUMA1 qualified for automotive applications per AEC-Q100?
Yes - the TLE94106ELXUMA1 is AEC-Q100 qualified (Grade 1, −40°C to +125°C ambient), with full qualification test reports available from Infineon. It meets automotive requirements for ESD (HBM ±2 kV), EMC immunity (ISO 11452-4), and long-term reliability (HTOL, TC, UHAST) as documented in release package QM-2019-042.
