TLE94110ESXUMA1 Overview
A half-bridge (H-bridge) motor driver is a power-converter topology that uses MOSFET half-bridges in push-pull configuration to drive DC loads bidirectionally. The TLE94110ES family sits in the motor-driver hierarchy as follows: motor driver -> half-bridge driver -> power management IC -> semiconductor. Compared with discrete MOSFET half-bridges, integrated multi-half-bridge drivers reduce PCB area, simplify thermal design by spreading dissipation across the exposed pad, and embed critical protection features such as overcurrent, open-load, and overtemperature shutdown.
Key features include 1.5A continuous output current per channel (up to 2A peak, depending on configuration), integrated PWM generators with adjustable dead time, open-load detection with programmable threshold on two outputs, and full short-circuit, overtemperature, and undervoltage protection. The 16-bit SPI daisy-chain capability allows multiple TLE94110ES devices to be controlled from a single MCU, supporting up to 12 half-bridges per chip and beyond via cascade.
The device is built on Infineon's smart power technology, combining DMOS output stages with CMOS logic on a single die. The exposed thermal pad provides a low thermal-resistance path to the PCB copper, enabling sustained 1.5A operation across all ten outputs simultaneously with proper board design. The wide 5.5V-20V input range covers 12V automotive bus systems including cranking transients when the input is buffered.
Typical applications include HVAC flap motors in automotive climate control, small DC and brushless DC (BLDC) motor driver stages, LED lighting modules with per-string current control, and generic multi-channel solenoid/relay drivers. Its 10-channel density makes it especially attractive for zonal body-control modules replacing discrete relay boxes.
When designing with this part, observe the exposed-pad PCB layout guidelines: use at least 6 cmΒ² of copper on top and bottom layers with thermal vias to spread heat from all 10 channels. Configure unused outputs as open-drain or tie them to the supply through a pull-up, and always enable the open-load detection on critical safety loads.

Typical Applications
TLE94110ESXUMA1 is suitable for 6 applications: Automotive HVAC Flap Motors, Zonal Body Control Modules, LED Lighting Modules, Small BLDC Motor Driver Stage, Multi-Channel Solenoid and Relay Drivers, Generic Multi-Channel DC Motor Control.
Automotive HVAC Flap Motors
The TLE94110ESXUMA1's 10 half-bridges, 5.5V-20V supply, and 150 C junction rating make it well-suited for HVAC flap motor drivers in automotive climate control. The 1.5A continuous per channel matches the typical 0.8A RMS draw of small DC gear motors used in air-distribution flaps, and the 16-bit SPI lets the body controller command 5-7 mode doors independently without parallel wiring. Open-load detection on two channels provides a safety diagnostic to detect stuck flaps on critical defrost and recirculation paths.
Recommended
Zonal Body Control Modules
Modern zonal E/E architectures consolidate door, seat, mirror, and lighting loads into one driver module - exactly the use case the TLE94110ESXUMA1 was designed for. Its 10 half-bridges can drive four window-lift motors, two seat-adjust motors, and four mirror-fold/LED loads, while the SPI daisy chain lets two TLE94110ES devices cover a 20-channel zone from a single 32-bit MCU. The 1.5A per channel is sufficient for small 12V DC motors, and the exposed-pad package keeps junction temperature in check when all 10 channels switch at 25 kHz PWM.
Recommended
LED Lighting Modules
The TLE94110ESXUMA1 doubles as a multi-channel LED driver when each half-bridge is used in low-side switch configuration with an external boost or buck supply. The 1.5A per channel is enough for 5-10W automotive LED strings (running them at 350-700 mA), and the integrated PWM generator with adjustable dead time supports color-mixing and dimming without burdening the host MCU. Open-load detection on two outputs can monitor critical safety lights (DRL, turn signal) for fail-safe diagnostics required by ECE-R148.
Recommended
Small BLDC Motor Driver Stage
Although primarily a half-bridge driver, the TLE94110ESXUMA1 can build a 3-phase BLDC driver by paralleling 3+ half-bridges per phase, supporting 3-4 small sensorless BLDC fans or pumps per chip. The 1.5A continuous is sufficient for 5-15W BLDC loads (radiator fans, water pumps, fuel pumps), and the SPI-controlled dead time adjustment prevents shoot-through. Pairing the TLE94110ESXUMA1 with the TLE9180D32QKXUMA1 gate driver extends the design to higher-current BLDC applications up to 30A.
Recommended
Multi-Channel Solenoid and Relay Drivers
Industrial and agricultural machinery often require 8-16 channels of solenoid or relay control; the TLE94110ESXUMA1 covers 10 of those in one IC. The wide 5.5V-20V supply handles 12V and 24V battery systems, and the integrated flyback (free-wheeling diode) capability on each half-bridge eliminates 10 external diodes. The 1.5A per channel covers most small solenoids and pilot relays used in hydraulic valve banks, while open-load detection verifies coil continuity at power-up.
Recommended
Generic Multi-Channel DC Motor Control
For non-automotive industrial, robotics, and IoT edge applications, the TLE94110ESXUMA1 offers one of the highest channel densities in a 24-pin package. The 5.5V minimum supply allows direct operation from a 6V battery or 5V boost rail, while the SPI daisy chain lets a Raspberry Pi or ESP32 control up to 30+ channels via 3 cascaded chips. The exposed-pad package and 150 C junction temperature support continuous full-load operation in enclosed industrial housings with proper thermal vias.

Key Differentiators
- 10 half-bridges in a 24-pin package - highest channel density in PG-TSDSO-24 (vs TLE94112ESXUMA1)
- 16-bit SPI with daisy-chain, integrated PWM generator, and open-load diagnostics (vs TLE92633BQXXUMA2)
- Wide 5.5V-20V supply covers 12V automotive and 24V industrial buses (vs TLE94110ELXUMA1)
Design Notes
The TLE94110ESXUMA1 dissipates up to 0.6W per channel at 1.5A and 100% duty, so 10 channels fully loaded is 6W. With a PG-TSDSO-24 exposed pad (theta_JA approximately 35 C/W on a 4-layer JEDEC test board, but 50-60 C/W on a typical 2-layer design), junction temperature can climb 200-300 C above ambient if the thermal pad is not properly soldered. Use at least 6 cmΒ² of copper on top and bottom layers, stitch with 9 thermal vias (0.3 mm drill) directly under the exposed pad, and never rely on the package alone for 10-channel full-load operation.
Place all 4 supply pins (VS, VS, GND, GND) with wide copper pours directly into the input battery bus. The 1.5A switching currents of 10 half-bridges return through GND, so a split or starved ground plane will cause ground-bounce false triggering of the open-load comparator. Keep the SPI traces (CSN, SCLK, SDI, SDO) under 50 mm and away from OUT traces; route SDO with a 33 ohm series resistor to dampen ringing with the MCU's input capacitance.
Do not leave unused outputs floating - configure them as open-drain or pull them to VS through a 10 kohm resistor. The TLE94110ESXUMA1 treats floating outputs as an open-load fault and will set the corresponding SPI status bit, which can flood the diagnostic state machine. Also, the 5V VCC output is intended for internal logic only; do not source more than 5 mA externally or the internal LDO will drop out. For MCU supply, add a separate Infineon TLS810B1LDV50XUMA1 LDO.
When paralleling outputs to get 12 half-bridges or higher current (3A or 5A), keep the paralleled traces symmetric and identical in length; a 5 mm mismatch creates 20% current imbalance between the paralleled FETs at 1 kHz PWM. Add 1 ohm gate resistors in each output path to isolate the FETs from shared gate-drive ringing, and use the SPI's readback to verify current sharing via the open-load thresholds during development.
