Product details
Overview
TLE84110ELXUMA1 from Infineon Technologies is a 10-channel protected Deca-Half-Bridge driver IC for automotive DC motor control, featuring 16-bit SPI interface, AEC-Q100 qualification, 1A minimum overcurrent threshold, and operation modes including forward, reverse, brake, and high-impedance. It drives up to 5 DC motors in parallel or 9 in sequential configuration in HVAC flap actuator systems.
For engineers reviewing the TLE84110ELXUMA1 datasheet, TLE84110ELXUMA1 pinout, TLE84110ELXUMA1 application, or TLE84110ELXUMA1 equivalent, key selection criteria include SPI-controlled multi-motor sequencing, integrated open-load/short-circuit/overtemperature diagnostics, thermal performance of the exposed-pad SO-14 package, and pin/SW compatibility with TLE84106EL.
Technical Context
The TLE84110ELXUMA1 integrates ten independent half-bridge power stages with high-side and low-side drivers, charge pump, bias generation, and comprehensive fault monitoring (open load, short-to-battery, short-to-ground, overtemperature, undervoltage, overvoltage). Each channel supports programmable current limiting and diagnostic feedback via dedicated status bits.
Its 16-bit SPI interface enables bidirectional communication for command input (mode, enable, PWM duty), status readback (error flags per channel), and configuration register access. The device operates from 5.5 V to 28 V supply (VS) and features an inhibit (INH) pin for system-level shutdown.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-channel half-bridge motor driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLE84106ELXUMA1 | 6-channel version; identical pinout, SPI protocol, and diagnostic architecture | Lower channel count limits parallel motor count to 3; suitable for simpler HVAC zones | Select when system requires fewer than 7 motor outputs and board space is constrained |
| BTS7200-2EPP | 2-channel high-side driver only; no integrated low-side or SPI interface | Requires external logic and gate drivers for full H-bridge operation; no built-in diagnostics | Choose only for legacy designs where discrete control logic already exists and diagnostic depth is secondary |
Compared with TLE84106ELXUMA1, the TLE84110ELXUMA1 adds four more half-bridges and supports larger flap configurations without increasing footprint; versus BTS7200-2EPP, it delivers complete SPI-managed motor control with diagnostics in a single package, reducing total BOM count and validation effort.

FAQ
What motor types and maximum load current does the TLE84110ELXUMA1 support?
The TLE84110ELXUMA1 drives brushed DC motors with peak output current up to 2.8 A per channel (typical) and minimum overcurrent detection threshold of 1 A. It supports both parallel (up to 5 motors) and sequential (up to 9 motors) configurations, with each half-bridge capable of handling inductive loads up to 100 mH and flyback energy suppression via internal clamping diodes.
How does the SPI interface handle fault reporting and command execution?
The 16-bit SPI interface uses separate SDI/SDO lines for full-duplex communication: each write cycle sends a command word (e.g., OUTx mode, PWM duty), while each read cycle returns a status word containing 10 channel fault bits (open load, short, overtemp), global flags, and temperature code. The INT pin asserts asynchronously on any active fault, enabling interrupt-driven error handling.
Is the TLE84110ELXUMA1 pin-compatible with earlier Infineon motor drivers?
Yes - the TLE84110ELXUMA1 shares identical pinout, package (SO-14 EP), and SPI register map with the TLE84106ELXUMA1, enabling drop-in replacement in existing layouts. Software drivers require only minor updates to address additional channels; no hardware changes are needed for migration from 6- to 10-channel operation.
What thermal management considerations apply to the exposed-pad SO-14 package?
The exposed thermal pad must be soldered to a minimum 100 mm² copper pour on the PCB with ≥4 thermal vias (0.3 mm diameter) connecting to inner ground planes. At 70 °C ambient and 1 A per channel continuous load, junction temperature remains below 125 °C with this layout, satisfying AEC-Q100 Grade 1 requirements without forced airflow.
