TLE9104SHXUMA1 - 4-Ch 3A SPI Low-Side Switch | Infineon
MPN: TLE9104SHXUMA1 ✓ Hoạt độngTLE9104SHXUMA1 Tóm tắt
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 cm² of copper area to the exposed pad per channel of continuous current, and respect the SPI timing budget for sequential reads during fault scans.

Ứng dụng tiêu biểu
TLE9104SHXUMA1 phù hợp cho 7 Áp dụngs: 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.

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 °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.

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.

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.

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.

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.

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.

Ghi chú thiết kế
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 mΩ 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 cm² of PCB copper on a 1-oz layer to keep junction rise below +50 °C above 85 °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 µF 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.
