ITS4075QEPDXUMA1 Overview
A smart high-side switch is a semiconductor relay built around one or more N-channel power MOSFETs that connect a load to the positive supply rail under logic-level control. Within the broader power management taxonomy, the ITS4075Q-EP-D belongs to the family of high-side switches (also called load switches or PROFETs), which sit between the load driver IC hierarchy and discrete MOSFETs. Infineon's PROFET+ family specifically targets harsh 24 V industrial and 12 V automotive environments with on-state resistance values in the 30 mΩ to 200 mΩ range, four protective functions plus diagnosis, and reverse-polarity support through external components.
Key features include a wide 5 V to 45 V operating supply range, 2.6 A peak current capability, built-in charge pump for full N-channel drive, and per-channel current proportional sensing via the IS pin. The exposed-pad PG-TSDSO-14 package achieves RthJA values appropriate for 2 A continuous operation on standard JEDEC 1s0p test boards, and the 150 °C maximum junction temperature allows high transient handling for inductive loads. Slew-rate control at each output reduces EMI on switch edges.
Typical applications include industrial PLC digital outputs, 24 V solenoid and valve drivers, body control modules (BCM) for lighting and seat motors, and ground-isolated load multiplexing in process control. The PG-TSDSO-14 (TSSOP-14 with exposed pad) footprint is JEDEC-compatible with standard 14-pin SMD placement.
When designing with this part, reserve headroom for the charge-pump supply and ensure the 150 Ω GND resistor (for reverse-polarity operation) or reverse-current diode is sized correctly per datasheet guidance. Multi-channel synchronization requires careful ground layout to prevent cross-talk on the shared IS sense line.

Typical Applications
ITS4075QEPDXUMA1 is suitable for 6 applications: Industrial PLC Digital Output Module, 24V Solenoid and Valve Driver, Automotive Body Control Module (BCM), Lighting Control Systems, Process Control Load Multiplexer, Building Automation HVAC Actuators.
Industrial PLC Digital Output Module
The ITS4075QEPDXUMA1 is ideally suited for industrial PLC digital output modules driving 24 V loads. Its 45 V maximum supply rating covers 24 V industrial rails plus transient headroom, while 75 mΩ RDS(ON) keeps conduction loss low enough that four channels can be operated continuously at 2 A each without exceeding the PG-TSDSO-14 thermal envelope. The integrated diagnostic current-sense pin feeds back per-channel load current to the PLC CPU, enabling IEC 61131-3 fault detection (open load, short circuit, over-temperature) without external sense resistors. Compared to discrete MOSFET solutions, the ITS4075QEPDXUMA1 integrates overcurrent, short-circuit, over-temperature, overvoltage, and undervoltage-lockout protection in one chip, reducing BOM count by approximately 60%.
Recommended
24V Solenoid and Valve Driver
The ITS4075QEPDXUMA1 provides robust solenoid and hydraulic-valve drive for industrial process control. With four channels each capable of 2 A continuous and 45 V supply headroom, it directly interfaces with 24 V DC solenoids, pneumatic valves, and relay coils common in factory automation. The built-in charge pump drives the N-channel MOSFETs fully on, minimizing Rds-on losses and thermal stress during PWM proportional valve control. The per-channel current sense output enables closed-loop current control for proportional solenoid positioning, where precise current sets the magnetic force and thus valve stroke. Compared to electromechanical relays, the ITS4075QEPDXUMA1 offers 10x faster switching, 100x longer life, and built-in wire-break detection via the diagnostic pin.
Recommended
Automotive Body Control Module (BCM)
The ITS4075QEPDXUMA1 serves automotive body control modules driving lighting, seat motors, mirror heaters, and other resistive or inductive 12 V loads. Its wide -40 °C to +150 °C junction temperature range handles under-hood and cabin thermal extremes, while the 45 V supply rating survives 12 V automotive load-dump transients up to 35 V per ISO 7637-2. Four integrated channels in one PG-TSDSO-14 package minimize PCB area, which is critical for the space-constrained BCM form factor. Compared to automotive-grade discrete solutions, the ITS4075QEPDXUMA1 integrates ISO 16750-compliant protection (overvoltage, reverse battery with external 150 Ω resistor, load-dump) into a single 14-pin device.
Recommended
Lighting Control Systems
The ITS4075QEPDXUMA1 efficiently drives LED lighting strings, architectural lighting, and emergency lighting loads in commercial and industrial settings. Each of the four channels can drive up to 2 A, enabling parallel control of multiple LED fixtures, dimming circuits, or RGBW channels. The fast switching speed (sub-microsecond) supports PWM dimming at frequencies above 1 kHz without visible flicker, while the current-sense output enables closed-loop brightness feedback for constant-current LED operation. Compared to electromechanical lighting relays, the ITS4075QEPDXUMA1 offers silent operation, infinite cycle life, and built-in fault detection that distinguishes open LED strings from normal off-state.
Recommended
Process Control Load Multiplexer
In industrial process control, the ITS4075QEPDXUMA1 functions as a 4-channel load multiplexer for sensors, actuators, and field instruments sharing a common 24 V rail. Each channel's diagnostic current-sense output detects open-load, short-circuit, and partial-load degradation events that would otherwise require manual inspection. The integrated charge pump ensures full enhancement of the N-channel MOSFETs at all supply voltages, maintaining low RDS(ON) even at the 8 V minimum battery-rail dip. Compared to solid-state relays (SSRs), the ITS4075QEPDXUMA1 provides integrated logic-level control directly from the PLC's 3.3 V or 5 V GPIO, eliminating external driver circuitry.
Recommended
Building Automation HVAC Actuators
The ITS4075QEPDXUMA1 drives HVAC actuators in building automation systems, including damper motors, valve actuators, and relay coils in 24 V building control networks. Its 45 V maximum supply tolerates the overvoltage transients common in long cable runs within commercial buildings, and its four-channel integration reduces wiring complexity by combining four actuator outputs into one 14-pin device. The diagnostic current-sense pin enables per-channel health monitoring, which is essential for predictive maintenance in large building automation installations where manual inspection of every damper or valve is impractical. Compared to conventional relay panels, the ITS4075QEPDXUMA1 reduces panel size by approximately 70% while adding diagnostic capability.

Key Differentiators

- Wide supply voltage range for industrial 24V bus compatibility (vs TPS4H160AQPWPRQ1)
Design Notes
Estimated: at VIN=24 V driving four 2 A loads with 75 mΩ RDS(ON), the ITS4075QEPDXUMA1 dissipates approximately I²R = (2 A)² × 0.075 Ω × 4 channels = 1.2 W total. The PG-TSDSO-14 exposed pad reduces θJA to roughly 35 °C/W on a 4-layer JEDEC EIA/JESD51 1s0p test board, giving a junction rise of about 42 °C above ambient at full 4-channel load. For continuous operation at the 2.6 A absolute maximum, designers must add a copper thermal land of at least 100 mm² to keep Tj below 150 °C, per Infineon datasheet thermal derating guidance.
Reverse-polarity protection on the ITS4075QEPDXUMA1 requires an external 150 Ω power resistor between the GND pin (pin 5) and the system ground, per Infineon datasheet. This resistor carries the full load current during a reverse-battery event and must be rated for the worst-case continuous load. Alternative implementations use a reverse-current diode in the GND path. Without this external component, applying a reverse supply will permanently damage the device.
Place the VBB (pin 11) decoupling capacitor as close as possible to the device using a 100 nF ceramic plus a low-ESR 10 µF bulk capacitor to handle the inrush current during channel turn-on with inductive loads. The exposed pad (EP) must be soldered to a copper thermal land with at least 8 thermal vias to the inner power plane. Keep the IS (pin 8) analog sense trace short and shielded from the OUT1-OUT4 switching traces to prevent capacitive coupling from corrupting the diagnostic current-sense signal.
Compliance Information
RoHS and REACH compliant per Infineon product page. ITS4075Q-EP-D is the industrial-grade variant; for AEC-Q100 automotive grade, consider ITS4075QEPDXUMA1 derivative ITS4075Q-EP-D with automotive screening, or cross-brand TPS4H160AQPWPRQ1.
