Typical Applications
BTT62001ENAXUMA1 is suitable for 6 applications: Automotive Exterior Lighting, Industrial 24V PLC Output Module, HVAC Actuator and Valve Driver, Agricultural and Construction Vehicle Body Electronics, 24V Relay and Contactor Coil Driver, Solar Tracker Motor Driver.
Automotive Exterior Lighting
The BTT62001ENAXUMA1 drives 24V automotive lamps including turn signals, brake lights, and tail lamps. Its 200 mΩ Ron limits conduction losses to roughly 300 mW at 1.5 A, keeping the DSO-8 exposed-pad package within thermal limits when soldered to ≥1 cm² copper. Integrated short-circuit and overload protection handles the high inrush of cold tungsten filaments (up to 10× steady-state current), while the IS diagnostic pin reports open-load failures to the BCM for bulb-out detection in compliance with FMVSS lighting standards.
Recommended
Industrial 24V PLC Output Module
In industrial PLC digital output modules, the BTT62001ENAXUMA1 switches 24 V solenoids, relay coils, and indicator lamps directly from logic-level microcontroller signals. Its 5 V-48 V operating range supports both 24 V DC industrial rails and 48 V battery/photovoltaic systems. The 200 mΩ Ron minimizes voltage drop across the switch - critical for maintaining solenoid pull-in thresholds. Infineon Smart6 HV technology provides load-dump and reverse-battery transient immunity for harsh factory environments, while the IS pin enables per-channel fault diagnostics for predictive maintenance.
Recommended
HVAC Actuator and Valve Driver
The BTT62001ENAXUMA1 drives HVAC damper motors, water valves, and proportional solenoid actuators from a 24 V supply. Its 1.5 A continuous rating handles typical actuator currents with margin, and integrated thermal shutdown protects against stalled-motor conditions. The exposed pad of the PG-TDSO-8-31 package provides a low thermal resistance path for sustained actuator holding currents. The diagnostic IS output signals valve-position feedback faults to the climate controller, supporting ASIL-aware fault detection in zoned HVAC systems.
Recommended
Agricultural and Construction Vehicle Body Electronics
In off-highway vehicles such as tractors, harvesters, and excavators, the BTT62001ENAXUMA1 switches 24 V work lights, beacon lamps, and auxiliary loads. The wide 5 V-48 V operating voltage range accommodates crank-dip and load-dump transients common in heavy-duty vehicle electrical systems. Infineon's Smart6 HV technology provides the ruggedness required for IEC 61000-4-2/-4/-5 EMC compliance, while the integrated reverse-battery protection eliminates the need for an external protection diode. The exposed pad layout supports high ambient under-hood temperatures up to 105 °C.
Recommended
24V Relay and Contactor Coil Driver
The BTT62001ENAXUMA1 provides a logic-controlled interface between a 3.3 V or 5 V microcontroller and 24 V relay or contactor coils used in industrial control panels and battery management systems. Its 200 mΩ Ron drops only ~300 mV at 1.5 A, leaving most of the 24 V across the coil for reliable pull-in. Reverse-battery protection safeguards the driver from mis-wired installations, and the integrated current limit prevents contactor-coil inrush from damaging the driver. The exposed pad keeps the part cool during continuous duty in relay-logic panels.
Recommended
Solar Tracker Motor Driver
In photovoltaic solar tracker systems, the BTT62001ENAXUMA1 drives 24 V DC actuators that reposition solar panels throughout the day. Its 48 V maximum operating range supports battery banks that can rise above nominal during equalization charging. The 200 mΩ Ron minimizes power dissipation in continuously-cycled tracker actuators, while over-temperature shutdown protects against stalled-motor conditions in the field. The exposed pad allows mounting on aluminum structural members that double as heatsinks, simplifying outdoor tracker electronics.

Design Notes
Estimated: At 1.5 A continuous with 200 mΩ Ron, the device dissipates roughly 0.45 W (P = I²R). With the PG-TDSO-8-31 exposed pad soldered to at least 1 cm² of 2 oz copper on a 1.6 mm FR-4 board, theta_JA is typically around 35 K/W. Junction temperature rise is therefore approximately 16 °C above ambient - well within the 150 °C limit. Without the exposed pad soldered properly, theta_JA exceeds 80 K/W and the device will thermal-shutdown at lower currents.
Use a star-ground topology with the BTT62001ENAXUMA1 GND pin connected to the analog ground plane at a single point near the MCU. Keep the high-current load traces (IN, OUT) short and wide - at least 1 oz copper, 50 mil wide for 1.5 A - to minimize voltage drop. Place a 100 nF ceramic decoupling capacitor close to the IN pin to suppress load-dump transients, and follow Infineon's reference layout for EMC compliance per IEC 61000-4 standards.
Do not exceed 48 V on the IN pin - the device's over-voltage clamp activates above this threshold and dissipates large amounts of power. Always check lamp inrush currents against the SOA graph; cold tungsten filaments draw 10× steady-state current and may trigger the short-circuit protection if not pre-conditioned. The IS pin output current is multiplexed with the DEN function - read the datasheet timing diagram carefully before sampling.
Compliance Information
RoHS and REACH compliance per Infineon product page. AEC-Q100 status not explicitly confirmed in verified web data; the trailing 'A1' in XUMA1 typically denotes automotive qualification but designers should verify in the datasheet header. HTSUS code 8542.39.0001, ECCN EAR99 per GlobalSpec datasheet mirror.
