Typical Applications
TLE75080ESDXUMA1 is suitable for 6 applications: Automotive Body Control Modules (BCM), Automotive LED Lighting Drivers, Industrial PLC Relay Driver Modules, 24V Industrial LED Matrix Modules, HVAC Blower and Seat Control Relays, Automotive Mirror and Seat Heater Control.
Automotive Body Control Modules (BCM)
The TLE75080ESDXUMA1 is well suited for 12 V body control modules driving lighting, HVAC blowers, seat-adjust relays, and mirror heaters. Each of its 8 channels delivers 330 mA with active current limiting, matching the typical load profile of relays and small solenoids used in BCMs. The 16-bit SPI interface allows a single MCU to control dozens of channels across multiple daisy-chained ICs, reducing wiring harness complexity. The integrated Limp Home mode ensures outputs remain functional during 3.0 V cold-crank events, while load-dump survival to 40 V protects the system against ISO 7637-2 transients without external TVS components.
Recommended
Automotive LED Lighting Drivers
The TLE75080ESDXUMA1 drives LED strings up to 330 mA per channel with integrated PWM capability via SPI register control, eliminating external PWM generator ICs. Per-channel current limiting protects against LED short-to-ground faults, and open-load detection identifies burned-out LEDs in off-state diagnostics. The wide 4.5 V to 28 V supply range accommodates cranking dips and load-dump surges typical in 12 V automotive electrical systems. Combined with the exposed-pad thermal performance below 30 C/W on 2 oz copper, the part supports sustained LED matrix operation in tail-light, turn-signal, and interior ambient-lighting modules.
Recommended
Industrial PLC Relay Driver Modules
The TLE75080ESDXUMA1 drives 24 V industrial relay coils and indicator LEDs in PLC digital-output modules with 8 channels per IC. Each channel's 330 mA rating covers most signal-relay coils, and the active current-limit feature protects against relay-contact welding short circuits. The SPI diagnostic interface reports open-load and overcurrent conditions per channel, enabling predictive maintenance and reducing field-service calls. Wide operating temperature range of -40 C to +150 C supports deployment in factory automation cabinets and outdoor industrial enclosures without additional thermal management.
Recommended
24V Industrial LED Matrix Modules
The TLE75080ESDXUMA1 directly drives 24 V LED matrix panels up to 330 mA per channel, with each channel supporting PWM dimming via SPI-set duty registers. The exposed-pad package keeps junction temperature in check at high duty cycles on 2 oz copper, making it suitable for industrial signage and machine-status indicators. Diagnostic flags for open-load and short-circuit faults allow the host controller to detect failed LEDs without manual inspection. Operating from 4.5 V to 28 V also supports 12 V and 24 V industrial bus standards with a single design.
Recommended
HVAC Blower and Seat Control Relays
The TLE75080ESDXUMA1 controls relays in HVAC blower modules and seat-position actuators, replacing discrete MOSFETs and protection circuitry. Each channel's 330 mA continuous rating easily drives the typical 200 mA relay coil, while the integrated reverse-battery protection eliminates the need for an external blocking diode. SPI-based fault reporting identifies open relay coils and short-circuited wiring in production and during vehicle service. The Limp Home function ensures the HVAC fan and seat control remain operational during cranking, preventing transient ECU reset that could affect driver comfort.
Recommended
Automotive Mirror and Seat Heater Control
The TLE75080ESDXUMA1 manages resistive heating elements in mirrors and seats with 8 individually controllable channels at 330 mA each. PWM capability via SPI allows variable heat-output levels without external power-MOSFET circuitry. The integrated thermal shutdown protects heating elements from runaway faults if a thermal fuse fails, while per-channel current limiting detects wiring harness damage. The exposed-pad package handles the continuous dissipation of multi-channel heating loads within the tight PCB constraints of door modules and seat-control units.

Key Differentiators
- Integrated Limp Home mode for 3.0 V cranking transients (vs ITS724GFUMA1)
- 8 channels per IC in a single PG-TSDSO-24-21 package (vs BTS70021EPAXUMA1)
- Higher per-channel current than the lower-cost TLE75008 variant (vs TLE75008ESDXUMA1)
Design Notes
The PG-TSDSO-24-21 exposed thermal pad must be soldered to a continuous copper pour of at least 2 oz copper on top and bottom layers with at least 8 thermal vias under the pad. Estimated: with 2 oz copper and a 25x25 mm copper area, theta_JA is below 30 C/W, allowing all 8 channels at 330 mA continuous at 25 C ambient without thermal shutdown. Without adequate copper, junction temperature may exceed 150 C at full load.
Place a 100 nF ceramic bypass capacitor directly at the VBB pin and a 10 uF electrolytic bulk capacitor within 10 mm of the supply pin. Keep the SPI traces short and routed over an unbroken reference plane to avoid ground bounce corrupting SPI reads. The exposed pad must NOT share copper with high-current OUTx return paths; keep OUTx copper pouring to the load side of the connector to minimize ground-loop transients coupling into the SPI interface.
Per-channel current-limit registers must be configured at startup; the default power-on state leaves current limit at the maximum value, which may be too high for some loads. Configuring the SPI watchdog is mandatory if the application relies on Limp Home mode - an unconfigured watchdog defaults to fail-safe but does not enable autonomous cranking behavior. Do not connect the WAKE pin to VBB without a series resistor; direct connection may exceed the ESD clamp current rating during transients.
Compliance Information
AEC-Q100 qualified for automotive applications. RoHS and REACH compliant per Infineon product page. Halogen-free and lead-free packaging confirmed by Partstack material declaration (JESD-609 e3 terminal finish).
