TLE9104SHXUMA1 Overview
A multi-channel low-side driver IC is an integrated circuit that switches multiple resistive or inductive loads to ground using internal MOSFETs, controlled by a digital logic interface. Low-side drivers sit at the bottom of the load path (load connected to supply, switch to ground) and belong to the broader family of power distribution switches, motor/valve drivers, and powertrain switches used in automotive body and engine ECUs.
Key features of the TLE9104SHXUMA1 include a 4.5 V to 28 V supply range, very low R_DS(on) per channel for high-efficiency switching, parallel-channel operation up to ~12 A, SPI-configurable dV/dt slew-rate control, and a 5 V VIO logic reference compatible with 3.3 V microcontrollers. The PG-DSO-20-88 exposed-pad package achieves a junction-to-ambient thermal resistance suitable for continuous 3 A per-channel operation with proper PCB copper area.
The device is built on Infineon's SMART7 power technology with embedded protection state machine, providing deterministic fault handling required for ASIL-rated systems. The diagnostic block reports per-channel fault status, open-load, short-to-battery, and overtemperature flags through dedicated SPI registers.
Typical applications include automotive engine-management loads (solenoid, valve, relay, injector drivers), transmission and gearbox control, body control modules, and 12 V / 24 V industrial switching.
When designing, allocate at least 6 cmΒ² of copper area to the exposed pad per channel of continuous current, and respect the SPI timing budget for sequential reads during fault scans.

Typical Applications
TLE9104SHXUMA1 is suitable for 7 applications: Engine-Management Solenoid and Valve Drivers, Transmission Gearbox Control, Body Control Module (BCM) Relay Replacement, Industrial 24 V Solenoid and Valve Banks, 12 V / 24 V Battery Management Load Switching, AEC-Q100 Powertrain ECU Auxiliary Drivers, LED Front-Lighting Driver Backbone.
Engine-Management Solenoid and Valve Drivers
The TLE9104SHXUMA1 is well matched to engine ECU solenoid and proportional valve loads because each of its four low-side channels delivers 3 A continuous with SPI-configurable dV/dt slew-rate control that limits inductive kickback. Per-channel diagnostic flags (open-load, over-current, over-temperature) feed directly into the engine management firmware loop, enabling limp-home strategies when a fault is detected. In a typical 4-cylinder direct-injection ECU, two channels drive boost-pressure solenoid valves and two drive camshaft phasers; the SPI daisy-chain reduces MCU pin count versus discrete drivers.
Recommended
Transmission Gearbox Control
Automatic and DCT transmission ECUs use multiple low-side drivers for shift solenoids, pressure regulators, and lockup clutches. The TLE9104SHXUMA1's 4-channel architecture drives shift solenoids directly while the SPI bus reports per-channel current and temperature for adaptive shift-quality calibration. Operating up to +150 Β°C junction, the device sits near transmission oil temperature without active cooling. AEC-Q100 qualification and ASIL-ready documentation support ISO 26262 functional-safety integration.
Recommended
Body Control Module (BCM) Relay Replacement
Replacing mechanical relays in a BCM with the TLE9104SHXUMA1 reduces PCB area and eliminates coil flyback issues. Each of the four channels sinks up to 3 A for lighting, mirror-fold, or seat-adjustment relays, and SPI diagnostics report open-load (bulb-out) conditions over CAN to the instrument cluster. Compared to discrete N-MOSFETs plus gate drivers, the integrated over-temperature shutdown and parallel-channel capability simplify BCM thermal design and enable software-controlled load shedding during cranking.
Recommended
Industrial 24 V Solenoid and Valve Banks
Beyond automotive, the 4.5 V to 28 V VDD range lets the TLE9104SHXUMA1 drive industrial 24 V hydraulic or pneumatic solenoid banks in factory automation and process control. Each low-side channel switches solenoids to ground with SPI-monitored current, and configurable dV/dt protects downstream valve coils. Paralleling channels supports 6 A or 9 A proportional valves without external FETs. SPI diagnostics integrate with PLC backplanes for predictive maintenance.
Recommended
12 V / 24 V Battery Management Load Switching
Battery-management systems (BMS) need reliable load disconnect for pre-charge resistors, heaters, and balancing circuits. The TLE9104SHXUMA1 switches pre-charge paths, low-voltage heaters, and cell-balancing resistors with SPI control from the BMS MCU. Per-channel over-current detection protects against short-circuit heater faults, while the 28 V VDD rating tolerates load-dump transients on 24 V truck and bus batteries.
Recommended
AEC-Q100 Powertrain ECU Auxiliary Drivers
Within an engine ECU, the TLE9104SHXUMA1 typically handles auxiliary loads such as the oil-control valve, variable-intake manifold runner, canister-purge valve, and starter relay interface. Four SPI-controlled channels reduce the discrete MOSFET count and the SPI diagnostic bus feeds the engine-management loop. The PG-DSO-20-88 package and 4.5 V to 28 V VDD range are co-designed with Infineon's SBC family such as the TLE9262-3BQX for plug-and-play powertrain solutions.
Recommended
LED Front-Lighting Driver Backbone
Matrix-LED headlamp controllers use the TLE9104SHXUMA1 to drive pixel-driver FETs and high-current LED strings via SPI-controlled low-side switching. Each channel handles LED enable, fault detection, and PWM dimming coordination; per-channel open-load detection identifies failed pixel LEDs for driver-feedback reporting. Operating from the 12 V automotive rail with load-dump tolerance, it co-exists with high-side LED drivers such as the LITIX Basic family for a complete matrix-LED architecture.

Key Differentiators

- Configurable dV/dt slew-rate control (vs ITS4100SSJNXUMA1)
Design Notes
Estimated: at 3 A continuous per channel and VIN = 14 V with the load return at 0 V, each low-side MOSFET dissipates roughly VIN * I_load * R_DS(on) / R_DS(on) factor; with a typical R_DS(on) of ~50 mΞ© this is ~0.45 W per channel or ~1.8 W for four channels. The PG-DSO-20-88 exposed pad requires at least 6 cmΒ² of PCB copper on a 1-oz layer to keep junction rise below +50 Β°C above 85 Β°C ambient. Add thermal vias under the exposed pad per IPC-2221 if multiple layers are available.
Place the VDD and VIO decoupling capacitors (typically 100 nF ceramic in parallel with 10 Β΅F electrolytic) within 3 mm of the respective pins. Keep the SPI traces short and route the SCLK/SDO/SDI/CSN bundle over a continuous ground pour; the exposed pad must be soldered to a copper area with a minimum of 4 thermal vias for heat extraction. Pin 1 orientation follows the standard PG-DSO notch convention.
Do not exceed 28 V on VDD; load-dump transients above this require an external TVS clamp. Always pull RESN high after VIO stabilizes; failure to do so leaves channels in high-impedance and the SPI registers in reset. For inductive loads above 1 mH, add an external free-wheeling diode across the load even though the device has internal clamping paths - the internal clamp is sized for short transients only.
Run the SPI bus at the slowest SCLK that meets the application's fault-scan deadline - this reduces switching noise coupling into analog sensor channels on the same ECU. Daisy-chain multiple TLE9104SH devices by tying CSN together and chaining SDO of one to SDI of the next; the 16-bit frame format auto-extends per the Infineon SPI protocol.
