TLE8082ESXUMA1 Présentation
Engine management PMICs are highly integrated power and driver ICs that combine a microcontroller-compatible supply rail, multiple low-side switches, communication interfaces, and protection features in a single package. They sit at the top of the small-engine ECU power tree, replacing discrete regulators plus discrete MOSFETs and reducing BOM count, PCB area, and quiescent losses. The TLE8082ES family is positioned in Infineon's TLE808x small-engine PMIC lineup.
Key features include integrated 5 V linear or switching supply, four low-side driver outputs for injector or relay control, SPI-configurable diagnostics, and built-in protection such as thermal shutdown, overcurrent limiting, and reverse-battery robustness. The PG-TSDSO-24 exposed pad provides a thermal resistance path that supports sustained operation of the integrated drivers at engine ambient temperatures up to the AEC-Q100 automotive qualification envelope.
Architecturally, the TLE8082ESXUMA1 combines an internal bandgap reference, a pre-regulator, a 5 V post-regulator, four gate drivers for low-side N-channel MOSFETs, and an SPI slave for microcontroller communication. This integration lets a small 32-bit MCU control fuel injection, ignition, and sensor power without auxiliary driver ICs.
Typical applications include small-engine ECUs for motorcycles, scooters, mopeds, marine outboards, generators, and handheld power equipment. The wide VIN range and integrated drivers are tailored to single-cylinder and small-displacement powertrains where PCB area and BOM cost dominate the design.
When designing with this part, ensure the exposed pad is soldered to a sufficient copper pour for thermal relief; sustained low-side driver currents can dissipate significant power. Use the SPI watchdog to detect MCU lockup, and follow Infineon's small-engine reference design for injector flyback sizing.

Applications typiques
TLE8082ESXUMA1 convient pour 7 applications: Motorcycle ECU Power Management, Small Single-Cylinder Engine Control, Marine Outboard Engine ECU, Scooter and Moped Engine Management, Portable Generator Engine Control, Lawn and Garden Equipment ECU, Two-Wheeler ABS Module.
Motorcycle ECU Power Management
The TLE8082ESXUMA1 is purpose-built for motorcycle and scooter ECUs, where it supplies 5 V to the host MCU and sensor rails while driving four low-side MOSFETs for injector, fuel pump, relay, and lamp control. Its 6 V to 40 V input tolerance covers 12 V battery cranking transients. SPI diagnostics enable OBD-style fault reporting and real-time current monitoring, critical for emission-regulated single- and twin-cylinder engines.
Recommandé
Small Single-Cylinder Engine Control
For handheld power tools, generators, and small single-cylinder engines, the TLE8082ESXUMA1 integrates what would otherwise be three or four discrete ICs: a 5 V regulator, low-side gate drivers, and an SPI-configurable diagnostic block. The PG-TSDSO-24 exposed pad handles thermal dissipation from sustained driver currents. AEC-Q100 qualification ensures reliability under hood-mounted ambient conditions.
Recommandé
Marine Outboard Engine ECU
Marine outboard engines run on 12 V marine batteries with significant load-dump and reverse-polarity stress. The TLE8082ESXUMA1's 6 V to 40 V input envelope, AEC-Q100 qualification, and integrated protection features make it well suited to outboard ECU designs. SPI diagnostics report injector and sensor faults back to the engine management display, supporting NMEA-2000 fault telemetry.
Recommandé
Scooter and Moped Engine Management
Entry-level scooters and mopeds require compact, low-cost ECUs with integrated diagnostics. The TLE8082ESXUMA1's small 24-pin TSSOP footprint, integrated 5 V rail, and SPI programmability cut BOM cost and PCB area. Its low quiescent current helps meet standby-current budgets for vehicles with long parked periods. SPI watchdog detects MCU lockup and safely shuts down actuators.
Recommandé
Portable Generator Engine Control
Portable generators run in harsh environments with wide temperature swings, vibration, and dirty electrical loads. The TLE8082ESXUMA1's AEC-Q100 qualification, integrated 5 V supply, and four low-side drivers handle fuel solenoid, choke, relay, and indicator control from a single IC. SPI diagnostics enable predictive maintenance and fault logging in commercial generator fleets.
Recommandé
Lawn and Garden Equipment ECU
Commercial lawn mowers, leaf blowers, and ride-on tractors increasingly use electronic engine management for emissions compliance. The TLE8082ESXUMA1's integrated 5 V rail and four low-side drivers handle throttle-by-wire, fuel injection, and operator-presence interlays in a compact TSSOP-24 footprint. SPI enables service-tool diagnostics for dealership service networks.
Recommandé
Two-Wheeler ABS Module
Although primarily an engine PMIC, the TLE8082ESXUMA1's 5 V supply, four low-side drivers, and SPI diagnostics are useful as auxiliary rails in motorcycle ABS modules that share the engine harness. The wide 6 V to 40 V input tolerates cranking and load-dump. SPI enables the ABS controller to read fault flags and reset drivers without external glue logic.

Principaux différenciateurs
- Only TLE8082ES variant ships on the 13-inch tape-and-reel form factor as the primary catalog part (vs TLE8082ES (tray))
- Highest volume-distribution ordering code in the Infineon small-engine PMIC family (vs TLE8082ESXUMA2 (alternate reel code))
- Integrated 5V + 4 low-side drivers + SPI in a single 24-pin TSSOP (vs Discrete LDO + 4 driver ICs solution)
Notes de conception
The PG-TSDSO-24 exposed pad is the primary thermal path for the four integrated low-side drivers. Estimated: at sustained 4 x 250 mA driver output with 2 V drop across each driver, total dissipation is approximately 2 W. The exposed pad must be soldered to a copper pour of at least 1 square inch (645 mm^2) to keep junction temperature within the AEC-Q100 envelope. Without sufficient copper, thermal shutdown may trigger under continuous load.
Place the input bulk capacitor (>= 47 uF) within 5 mm of the battery pin, and the 5 V output decoupling capacitor (>= 10 uF ceramic + 100 nF) directly at the 5 V pin. The exposed pad must have a continuous top-side solder mask opening and at least 8 thermal vias to the inner/ground plane to maximize heat transfer. Follow Infineon's small-engine reference layout for SPI trace routing to the MCU.
Do not exceed the 40 V absolute maximum input voltage; load-dump transients on a 12 V system can reach 35 V and on 24 V systems up to 60 V. Add an external TVS diode (e.g. 36 V SMBJ) at the battery pin for ISO 7637-2 pulse immunity. Verify SPI mode and clock polarity against the host MCU's configuration during bring-up; mismatched SPI mode causes silent driver faults.
